How many two digit numbers can be formed from the digits 2,4 and 6 if no digit is repeated

ABHISHEK KUMAR MISHRA   9 years AGO

Total no of sample space=3C2*2!=6
total no which is greater than 46=1*2=2
so probability=2/6=1/3
i.e option 5)

Like? Yes (6) | No (2)  Md Shahnawaz Shahab   9 years AGO

total no of two digit nos formed by 2,4,6 = 6
nos above 46 are 62 and 64 = 2 no.s
therefore probability = 1/3

Like? Yes (3) | No   deepak kumar   9 years AGO

62 and 64 are 2 event.
24,26,42,46,62,64 are 6 possible event
Probability=2/6=1/3

Like? Yes (3) | No (1)  Bharat Bhushan Jha   9 years AGO

total no of way=3!
no greater then 46 will be
1.62
2.64
so total probability=2/3!=1/3 ANS

Like? Yes (2) | No    chaitanya   9 years AGO

total possible combinations 24 42 26 62 46 64
6 in total
of which only two are greater than 46

so 2/6=1/3

Like? Yes (3) | No (1)  ArunKumar   9 years AGO

the number of digit formed is 6 (24,26,42,46,64,62)

out of which greater than 46 is 2 ( 64,62)

Like? Yes (3) | No (2)   Anantharaman   9 years AGO

No# of ways to form a number >46 = 2

Total no# of outcomes = 6

Probability of forming a number > 46 = 2/6

=> 1/3

Option 5

Like? Yes (2) | No (1)  Ashfaque Hussain   9 years AGO

Two Digit Number can be formed: 3c2 = 3
Greater than 46 is only one 64
so probability = 1/3

Like? Yes (4) | No (3)   xyz   9 years AGO

total condition=6
favorable conditions=2(64 and 62)
so probability=2/6
1/3

Like? Yes (1) | No   Anand   9 years AGO

numbers are -- 24,26,42,46,62,64
no more than 46 is-- 62 and 64

so probability is= 2/6= 1/3

Like? Yes (3) | No (2)   Laltu banerjee   9 years AGO

n(e)=2 because only 62 and 64 is greater than 46.
n(s)=6 number we can formed using each digit only once.
hense n(e)/n(s)=2/6=1/3

Like? Yes (1) | No   Amresh kumar   9 years AGO

according to question we can have 24,42,26,62,46 and 64
from these six numbers problty for numbers greater than 46 is 2/6=1/3.

putting 6 at the tens place no. formed are 62,64 wich r only no.s greater than 46
2/6=1/3

Like? Yes (1) | No   prakash kumar   9 years AGO

2 digit no using 2,4,6=24,26,42,46,62,64

probability=2/6=1/3

Like? Yes (1) | No   Arun sauhu   9 years AGO

only two number can be formed

62 64 but not 66 x
as per question digit should not repeated

then only 2 numbers can be form
the total numbers can be form 3!
hence probablity is
2/6=1/3

Like? Yes (1) | No   ravi singh   9 years AGO

answer is 1/3
total=(24,26,42,46,62,64)
and greater than 46 is 64 and 62
hence=2/6=1/3

Like? Yes (1) | No    harjeet   9 years AGO

no. of combinations= 3*3=9
and greater than 46= 3(62,64,66)
p=3/9
=1/3

Like? Yes (1) | No   Roushan Singh   9 years AGO

Number of 2 digit no. formed (without repetition of digit)=6(24,42,46,64,26,62)
greater than 46 digits are 64 and 62
so probablity of getting no formed greater than 46=
2/6 which results in 1/3

Like? Yes (2) | No (1)  Saurabh Mishra   9 years AGO

total no of two digit no from 2,4,6=6
total no of digit from 2,4,6 which is grater than 46=2
so probability=2/6= 1/3

Like? Yes (1) | No   sravan   9 years AGO

total possible ways are- 24,26,42,46,62,64.
condition is - number> 46
probability is 2/6= 1/3

Like? Yes (1) | No   teena sirwani   9 years AGO

possible 2 digit no. is 6
no. greater than 46 is 2 so
p= 2/6=1/3

Like? Yes (1) | No   Dr.Dipin Singh   9 years AGO

only 2 numbers (62,64) are greater than 46 among 6 numbers (24,26,42,46,62,64) formed with given conditions.
so prob. = 2/6=1/3

Like? Yes (1) | No   Rituraj Singh   9 years AGO

for no. greater than 46 first digit should be 6 and two no. are possible 62,64 i.e. 2 no.
total no. possible are = 3*2=6
So, probability can be given as = 2/6=1/3

Like? Yes (1) | No   LAKSHMI ROJA   9 years AGO

Fix the 6 in tens digit place and the units place can be fillled in 2 way so the probability is 2/3c2=2/6=1/3

Like? Yes (1) | No   VIKASH KUMAR SHARMA   9 years AGO

no. of total ways = 3*2
thn 64 and 62 can v formed which is grtr thn 46
thrfor probability= 2/6= 1/3 ans

Like? Yes (1) | No   Deb Das   9 years AGO

total numbers formed 3*2=6.
as decimal digit can formed in 3 ways and unit digit in 2 ways. Now number greater than 46 formed is 62,64. So the probability is 2(/6)=1/3

Like? Yes (1) | No   sandy   9 years AGO

2 digits num formed using 2,4,6 are 24,26,42,46,62,64
numbers greater than 62,64
so probability of getting a num greater than 46 is 2/6=1/3

Like? Yes (3) | No (2)  jatin patware   9 years AGO

possible number=24,42,46,64,62,26
favourable=62,64
so ans is 2/6 i.e 1/3 so option 5 is correct

Like? Yes (1) | No    Anandapaul   9 years AGO

combinations are,
24

we can not place 2 or 4 in tens place.
we must place 6.
then 62,64.
totla outcomes=>24,26,42,46,62,64=>>6
hence 2/6=>1/3.

Following 6 two digit numbers can be formed using each digit only once, from the digits 2, 4, 6.
24, 26, 42, 46, 62, 64.
Out of this only 62 & 64 i.e. two numbers are greater than 46.
So probability is 2/6 = 1/3.
Hence option no.(5).

Like? Yes (1) | No (1)  Rats   9 years AGO

total combination = 3! = 6
which are
24, 26, 42, 46, 62, 64
there are only two numbers greater than 46
which are 62 and 64
So, probability for number greater than 46
=2/6=1/3...........Ans

Like? Yes (4) | No (4)  rohit kumar   9 years AGO

total two digits numbers formed by using 2,4 & 6 (w/o repitittion)=6
numbers greater than 46 is 62 & 64=2
so,
probability=2/6=1/3

grater than 46 no form

62,64
total no formed
246,264,426,462,624,642.

probability 2/6 =1/3

Like? Yes (1) | No (1)  kumar sundram   9 years AGO

two digit nos. using 2, 4 and 6 are 24, 26, 42, 46, 62 and 64.
so, no. of nos. of two digit using 2, 4 and 6 only once is 6.
the nos. which is greater than 46 are 62 and 66.
so, no. of nos. greater than 46 is 2.
thus, probability that the no. is greater than 46 is 2/6=1/3.

Like? Yes (1) | No (1)  Harsh Poddar   9 years AGO

two digit numbers formed by 2,4,6 without repeating the digits are 24,26,42,46,62,64
total numbers=6
numbers greater than 46=2
probability of getting more than 46=2/6=1/3
option 5

Like? Yes (1) | No (1)  Dharmendra Singh   9 years AGO

Ans 5) 2/6
Explanation : we can choose two digit number from 3-different number by 6 ways
for first place 3 ways 2nd place 2 ways total=3*2=6 ways
so total sample's event=6
and only two no. 62, 64 are favorable. so probability =2/6=1/3

Like? Yes (2) | No (2)  Grishma Shah   9 years AGO

the no. formed is 24,26,42,46,62,64.
total = 6
the no. greater then 46 is 62,64 =2
the probability = 2/6 = 1/3

Like? Yes (1) | No (1)  jagdish sharma   9 years AGO

two digit numbers r formd by 2,4,6 is
24,42,26,62,46,64
Only 62 and 64 greater then 46
Probability=2/6=1/3

Like? Yes (1) | No (1)  Triloki Shaw   9 years AGO

total two digit no. formed by 2,4,6 is 3P2=6
two digit no greater than 46 is 6 at tens place and unit place being formed in 2! ways=2
therefore probability= 2/6
i.e., 1/3 ans.

Like? Yes (3) | No (3)  Rituparna Bhattacharyya   9 years AGO

total no of two digit nos formed b 2,4,6 = 6
nos above 46 are 62 and 64
therefore prob = 2/6 = 1/3

Like? Yes (1) | No (1)  Jyothi   9 years AGO

total possibility 3!
possibility for the number greater than 46 is 2!
probability=2!/3!=1/3

Like? Yes (1) | No (1)  Dharmendra Kumar Rajak   9 years AGO

Given digits are 2,4,6
we have to make two digits numbers using given numbers
now,
[___] [___]
3ways 2ways
So,
total number of permutation =3*2=6
i.e. [24,26,46,42,62,64]
out of which only two are greater than 46 i.e.62,64
So probability of outcome of number which are greater than 46
will be
p=2/6;
p=1/3;
So option (5) is correct.

Like? Yes (1) | No (1)  Harjit kaur   9 years AGO

Total no of two digit(s)={24,26,42,46,62,64}
let e be the event two digit no greater than 46
e={62,64}
thus n(s)=6
n(e)=2
P(e)=n(e)/n(s)
=2/6
=1/3
thus option is 5
