P(1) = 12/52
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
P(2) = 12/52 * 11/51
p(3) = 12/52 * 11/51 * 10/50
P(4) = 12/52 * 11/51 * 10/50 * 9/49
The question is asking for the probability of 1, 2, 3 or 4 face cards.
Either-or probabilities are found by adding the individual probabilities.
