For each of the following, list the sample space and tell whether you think the events are equally likely:
a) Toss 2 coins; record the order of heads and tails.
b) A family has 3 children; record the number of boys.
c) Flip a coin until you get a head or 3 consecutive tails; record each flip.
d) Roll two dice; record the larger number (or simply the number in case of a tie).
