A pizza parlor has 13 different toppings available for its pizzas, and 2 of these toppings are pepperoni and anchovies. If a customer picks 2 toppings at random, find the probability that pepperoni is one of the toppings.

Round to four decimal places.

    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.
