2). Suppose that we have two dice, the first one being a regular
die, and the second weighted so that half the time it rolls a 1,
and half the time it rolls a 2 (it never rolls anything else). If
we choose one of these dice at random, and roll a 1, what’s the
probability...
A married couple has 3 children. What is the probability that

Boys and Girls: Suppose a couple plans to have
two children and the probability of having a girl is 0.50.

If a family has six children, is it more likely they will have
three boys and three girls, or four of one gender and two of the
other? Assume each child is a boy or a girl with equal probability,
independently of other children.
Helen has two children. Assume that the probability of each
child being a girl is 50%, and is independent with the gender of
