getting a number multiple of 22.

Required Answer :-

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

Sample space :-

{22,23,24,25,26,27,32,33,34,35,36,37,42,

43,44,45,46,47,52,53,54,55,56,57,62,63,

64,65,66,67,72,73,74,75,76,77}

n(S) = 36

Event A :- Two digit number is multiple of 22 .

A = {22,44,66}

n(A) = 3

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

P(A) = 3/36

P(A) = 1/12
