The probability that Santa Claus is coming to town is 0.8. The probability that the Grinch is coming to town is 0.15. Find the probability that both Santa Claus and the Grinch come to town if the two events are mutually exclusive.

Is this just Ø since they're mutually exclusive?

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

.8 * .15 = ?
