A box contains 4 tickets letter O, A, G, C. Two tickets will randomly be selected without replacement. What is the probability of selecting O then A in that order?

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
O = 1/4
A = 1/3
