No. of all possible outcomes = 113
(i) Perfect square numbers between 11 to 123 area 16,
25, 36, 49, 64, 81, 100, 121
No. of all favourable outcomes = 8
P(Number drawn is Perfect square) = 8/113
(ii) No. of multiples of 7 from 11, to 123 = 16.
14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91,98, 105, 112, 119
P(number drawn card is multiple of 7) = 16/113
