Consider purchasing a system of audio components consisting of a receiver, a pair of speakers, and a CD player. Let A1 be the event that the receiver functions properly throughout the warranty period, A2 be the event that the speakers function properly throughout the warranty period, and A3 be the event that the CD player functions properly throughout the warranty period. Suppose that these events are (mutually) independent with P(A1) = 0.95, P(A2) = 0.98, and P(A3) = 0.80. (a) What is the probability that all three components function properly throughout the warranty period? (b) What is the probability that at least one component needs service during the warranty period? (c) What is the probability that all three components need service during the warranty period?

Suppose that A and B are two independent events for which P(A)=0.23 and P(B)=0.65. Find each of the following: A. P(A|B)= B. P(B|A)= C. P(AandB)= D. P(AorB)=
Let A and B be events with P(A)=0.5, P(B)=0.55, and P(B|A)=0.9. Find P(A and B).
In a town, there are three bridges: Bridge A, Bridge B, and Bridge C. On any given day, the probability of each bridge being open for passage is as follows: P(A) = 0.4, P(B) = 0.3, and P(C) = 0.5. If a resident needs to cross all three bridges in succession, what is the probability of successfully crossing all three bridges without encountering any closures?
Events A and B are such that P(A)=0.30 and P(A or B)=0.60. Given that A and B are independent and non-mutually exclusive, determine P(B).
Let A and B be two events with P(A and Bc) = 1. Find P(B). Recall that Bc denotes the complement of the event B.
A rental car company offers two options when a car is rented. A renter can choose to pre-purchase gas or not and can also choose to rent a GPS device or not. Suppose that the events event that gas is pre-purchased event that a GPS is rented are independent with P(A) = 0.20 and P(B) = 0.65. (a) Construct a hypothetical 1,000 table with columns corresponding to whether or not gas is pre-purchased and rows corresponding to whether or not a GPS is rented. B A B= Not B Total A (b) Use the table to find P(A U B). Not A Total 1,000 Give a long-run relative frequency interpretation of this probability. In the long run, % of car renters will pre-purchase gas or rent a GPS, or both.
