(1) divisible by 7
(2)a number, which is a perfect square.

Answer 1

(1) divisible by 7 = 6/48=3/24
(2) perfect squares = 10/48 = 5/24

Answer 2

1. Total no. divisible by 7 = 7
All possible outcome = 48

Probability = 7/48

2. Total no. favourable to the event = 6
All possible outcome = 48

Probability = 6/48 = 1/8
