Question

If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)

Answer 1

12/13

Explanation:

A standard deck of cards has four suites

Total number of cards = 52

Total number of cards which are 4 is = 4

The probability that the card selected is 4 = 4/52 = 1/13

S, the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13
