1) Two athletic teams play a series of games; the first team to win 4 games is declared the overall winner. Suppose that one of the teams is stronger than the other and wins each game with probability 0.6, independant of the outcomes of the other games. Find the probability that the stronger team wins the series in exactly i games. Do it for i=4,5,6,7. Compare the probability that the stronger team wins with the probability that it would win a 2-out-of-3 series.

2) Suppose in the problem above, that the two teams are evenly matched and each has probability 1/2 of winning each game. Find the expected number of games played.

My son plays for the Hooks and his average is .333. Therefore I am going to assume the probability of him getting a hit is .333 for each time he bats. In a recent game he batted three times.
What was the probability of him getting at least one hit?
What was the probability of him getting two hits in the game?
What was the

1. A financial analyst estimates that the probability that the economy will experience a recession in the next 12 months is 20%. She also believes that if the economy enters a recession, the probability that her mutual fund will increase in value is 20%. If there is no recession the probability that the mutual fund will increase
