Question

In a standard deck of playing cards, there is a total of 56 cards, 4 of which are jacks. What is the formula for the probability of drawing a single jack from the deck of cards?

Answer 1

the probability is 1/14 (7.14%)

Explanation:

Since each card of the total of 56 equally likely to be chosen, then the probability is the ratio of the number of favourable outcomes divided by the total number of outcomes of the experiment. Thus the probability of getting a single Jack when there are 4 in 56 cards is

probability = number of favourable outcomes/ total number of outcomes = 4 Jacks / 56 different cards = 1/14 =0.0714 (7.14%)

thus the probability is 1/14 (7.14%)
