8. a) What are the odds of picking a jack, queen or king at random from a deck of cards?

b) What are the odds in favor of rolling a number greater than 3 on a die

Answer 1

a) 3/13

b) 1/2

Explanation:

a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.

b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.
