Exercise 52 Page 283

Determine the favorable outcomes and the possible outcomes.

P(yellow)=1/2

Practice makes perfect

We have been told that Steve has 20 marbles in a bag. There are 8 red, 2 blue, and 10 yellow marbles in the bag. We will find the probability of drawing yellow marble by using the Probability Formula. P=Favorable outcomes/Possible outcomes In this case, the favorable outcomes will be yellow marbles and the possible outcomes will be the total number of marbles.

P=Favorable outcomes/Possible outcomes

Favorable outcomes= 10, Possible outcomes= 20

P=10/20

a/b=.a /10./.b /10.

P=1/2

As a result, the probability of drawing yellow marbles is 12.
