In Exercise 2.151, you considered a model for theWorld Series. Two teams A and B play a series of games until one team wins four games. We assume that the games are played independently and that the probability that A wins any game is p. Compute the probability that the series lasts exactly five games. [Hint: Use what you know about the random variable, Y , the number of games that A wins among the first four games.]

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
