Question

Bob catches a train to work every day from monday to friday. the probability that the train is late on monday is 0.45. the probability that the train is late on any other day is 0.3. A day is chosen at random. Find the probability it is monday and the train is late

Answer 1

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

P(Monday) = 1/7

P(late) = .45
