Probability of picking pepperoni on the first pick = 1/13.
Assuming that customer does not want to "double up" on any topping, 12/13 for first pick for some other topping and 1/12 for second for pepperoni. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
Either-or probabilities are found by adding the individual probabilities to combine with first sentence results.
