In a standard deck of cards, there are a total number of
52 different card. From those 52 cards, 4 cards are numbered as five. Therefore
the probability of selecting a card of five is:
Probability = 4 / 52 = 1 / 13
Assuming that no replacement is made, so the probability
changes with each draw, since the total number of cards decreases from 52 to 51
to 50 and so on. Therefore this is not a simple event.
