We want to find the probability of randomly drawing a diamond card from a standard deck. We will find that the probability is P = 1/4.
So because we draw a card randomly, every card has the same probability of being drawn. Then the probability of randomly drawing a diamond card is equal to the quotient between the number of diamond cards and the total number of cards.
There are 13 diamond cards and a total of 52 cards, then the probability is:
P = 13/52 = 1/4
