4 Molly is going to see her favorite singer in concert. Of the first 200 people to enter
the concert venue, 10 will be randomly selected to meet the singer before the
show and 20 will be upgraded to front-row seating. Molly gets in line early so that
she is certain to be within the first 200 people to enter. Describe a simulation that
Molly could use to predict the probability that she will get to meet the singer and
be randomly selected to upgrade her seat.
