Probability of Dice and Cards

This week we learned about the probability of rolling dice and of drawing a card from a standard deck of 52 cards.

P(event A) = favorable outcomes/total number of outcomes

Ex 1. A. Find the probability of pulling out a face card out of a standard deck of cards.

12/52 = 3/13

B. Find the probability of pulling out a red card out of a standard deck of cards.

26/42 = 1/2

C. Find the probability of pulling out a spade out of a standard deck of cards.

13/52 = 1/4

D. Find the probability of pulling out a red face card out of a standard deck of cards.

6/52 = 3/26

Ex 2. A. What is the probability of rolling an even number with two dice?

18/36 = 1/2

B. What is the probability of rolling a 5 with two dice?

4/36 = 1/9
