Probability of getting a perfect square
= 8/96 = 1/12
Probability of getting a multiple of 7 = 13/96
Probability of getting a prime number less than 30 = 7/96
Probability of getting a perfect square between 91 and 99 = 1/96
= 8/96 = 1/12
Probability of getting a multiple of 7 = 13/96
Probability of getting a prime number less than 30 = 7/96
Probability of getting a perfect square between 91 and 99 = 1/96
