Answer:

a. 3/13 or 23.08%

b. 1/13 or 7.69%

c. 1/4 or 25.00%

d. 1/52 or 1.92%

Explanation:

Number of cards in a deck = 52

a. A face card

Considering there are four suits and each suit has three different face cards, the probability that the card is a cafe card is:


P_(F) =(3*4)/(52)\\ P_(F) =(3)/(13)

b. A queen

There are 4 queens in the deck, on of each suit, thus the probability of getting a queen is:


P_(Q) =(4)/(52)\\ P_(Q) =(1)/(13)

c. A spade

There are four suits with the same number of cards in a deck, therefore, the probability of getting a spade is:


P_(S) =(1)/(4)

d. A jack of spades

Since there are no repeated cards, there is only one jack of spades in a 52 cards deck:


P_(J+S) =(1)/(52)
