We're thinking about children again - let's stick
with our assumption that babies are boys with
probability 0.51, girls with probability 0.49, and
births are independent.
You're a researcher interested in large families:
as part of your latest project, you've decided to
interview 50 families in which there are exactly
eight children. The graph below illustrates the
possible outcomes for a single family. What's the
probability that you find one or more families in
which the children are all of the same gender (i.e.
all boys or all girls)?
