QuestionDuring
a bowling league tournament, the number of times that teams scored a strike
every ten minutes was recorded by a scorekeeper. The table below represents the probability
density function for the random variable X, the number of strikes every ten
minutes. Find the standard deviation of X.

• Round the final answer to two
decimal places.

QuestionA
player can play a game by rolling a fair die several times. The player can win
money based on the numbers rolled. The table shows the probability of each payout
amount (assume that the remaining probability has a payout of 0 so that the
probabilities add to 1). To the nearest dollar, what is the expected payout of
the game?
