Question

A cat had a litter of 5 kittens. If each sex is equally likely, what is the probability that 3 or less were female kittens? 0.3125 0.500 0.8125 0.2500

Answer 1

Probability of 3 or less = 0.8125.

Explanation:

This is a binomial probability distribution.

Prob(0 females) = 5C0(1/2)^5 = 0.03125

Prob(1 female) = 5C1 (1/2)^5 = 0.15625

Prob(2 females) = 5C2(1/2)^5 = 0.3125

Prob(3 females) = 5C3(1/2)^5 = 0.3125

Adding these we get 0.8125.
