Question

using the digit 2,4,6 find all the possible 2 digit no each digit used once. find the probability that the no is greater than 46

Answer 1

2 digit numbers using 2,4,6 without repetition = P(3,2) = 6

Possible numbers = 24,26,42,46,62,64

Probablity of getting a no. greater than 46 = 2/6 = 1/3

Answer 2

Sample space = (26,24,42,46,62,64)

Total possible cases = 6

Total favorable cases = 2

then probability (greater then 46) = 2/6 = 1/3
