An automobile insurance company divides customers into three categories, good risks, medium risks, and poor risks. assume taht 70% of the customers are good risks, 20% are medium risks, and 10% are poor risks. assume that during the course of a year, a good risk customer has probability 0.005 of filing an accident claim, a medium risk customer has a probability of 0.01, and a poor risk customer has probability 0.025. a customer is chosen at random.
a) what is the probability that the customer is a good risk and has filed a claim?
b) what is the probability that the customer has filed a claim?
c) given that the customer has filed a claim, what is the probability that the customer is a good risk?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

true !
