Assume that Team A beats Team B in 75% of the NBA games they play against each other (they play normal NBA games, i.e., 4 quarters, 12 minutes each, overtime if necessary).
a) Team A and Team B are playing a game and it is tied after the 3rd quarter. What do you think is the probability that Team A goes on to win?
b) They play again on a different night, and it is tied at the end of regulation. Overtime is about to start. What do you think is the probability that Team A goes on to win?
