Question

please solve it for me.....
que no. 23

Answer 1

Since the numbers on card are odd,
n(S) = 25
i) Probability of getting a no. divisible by 3 = n(E)/n(S) = 8/25
ii)Probability of getting a composite no. = n(E)/n(S) = 9/25
iii)Probability of not getting a perfect square = n(E)/n(S) = 4/25
iv)Probability of getting a multiple of 3 and 5 = n(E)/n(S) = 11/25
