Let S be the sample space

S = { 11, 12, ......123 }
n(S) = 112


Let A be the event of getting a square number

A ={ 16, 25, 36, 49, 64, 81, 100, 121 }
n(A) = 8
P(A) = n(A)/n(S)
=8/112
= 1/14

Let B the event

B = { 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119 }
n(B) = 16
P(B) = n(B)/n(S)
= 16/112
= 1/7
