Question

The probability that a couple will have two children, so that their first child is a boy and their second child is a girl, is 1/2.
True
False

Answer 1

these are 2 independent events
P(boy) first) = 1/2
P(girl second) 1/2

P(boy then girl) = 1/2 * 1/2 = 1/4

independent probabilities are multiplied

so false
