Two digit number is to be form from the numbers 2,3,4,5,6,7. Find the probability of getting a odd number.

Required Answer :-

Two digit number is to be form from the numbers 2,3,4,5,6,7.

Sample space :-

{23,24,25,26,27,32,34,35,36,37,42,43,45,

46,47,52,53,54,56,57,62,63,64,65,67,72,

73,74,75,76}

n(S) = 30

Event A :- Two digit number is odd number

A = {23,25,27,35,37,43,45,47,53,57,63,65,

67,73,75}

n(A) = 15

P(A) = n(A)/n(S)

P(A) = 15/30

P(A) = 1/2
