Question

A standard deck of cards has 52 cards of four different suits (diamonds, spades, hearts, clubs). Each suit consists of numbered cards 1 (Ace) to 10, followed by Jack, Queen and King (face cards). Express all your answers as a percent rounded to the nearest tenth of a percent, if necessary.

(a) If one card is drawn randomly from a deck, what is the probability that it is a spade?

(b) If one card is drawn randomly from a deck, what is the probability that it is not a face card?

(c) If one card is drawn randomly from a deck, what is the probability that it is a 5 of hearts or 7 of hearts?

(d) A card is drawn and then put back into the deck and reshuffled. Then a next card is drawn. What is the probability that both cards are clubs?

Answer 1

Explanation:

Brianna, the first 3 questions are just one choice type of probability questions, just figure out how many of the thing they are grouping

spades is a suit, there are 13 cards of one suit.

A) = 13/52 = 1/4

three face cards per suit 3*4 = 12

B) 12/52 = 6/26 = 3/13

C) 2/52 = 1 / 26

D) the tricky one

you draw once for 1/4 but then you draw again for 1/4

so it's 1/4 * 1/4 = 1/16
