Suppose that a family has 7 children. Also, suppose that the probability of having a boy is 12. Find the probability that the family has no more than 5 boys.
Added by Blanca M.
Step 1
We can use the binomial probability formula for this: P(X = k) = C(n, k) * p^k * (1-p)^(n-k) where n is the total number of children (7), k is the number of boys, p is the probability of having a boy (1/2), and C(n, k) is the number of combinations of choosing k Show more…
