3 Steve is going on holiday. The probability that he is delayed on his outward flight is 0.3 . The probability that he is delayed on his return flight is 0.2 , independently of whether or not he is delayed on the outward flight.
- Find the probability that Steve is delayed on his outward flight but not on his return flight.
- Find the probability that he is delayed on at least one of the two flights.
- Given that he is delayed on at least one flight, find the probability that he is delayed on both flights.
