You have enough information for the questions to be answered.

For example:

One card is drawn at random from a standard deck of 52 cards. Find the probability that the card is

a. a king


There are total 52 cards in the standard deck.

In a standard deck there are 4 (four) kings.

So probability of drawing a king from standard deck = 4/52 = 1/13
