Example Question #1 : Develop A Uniform Probability Model By Assigning Equal Probability To All Outcomes: Ccss.Math.Content.7.Sp.C.7a

Megan has a bag of marbles containing  pink marbles,  orange marbles,  green marbles, and  yellow marbles. What is the probability that Megan will pick a pink marble out of the bag?

Explanation:

In this problem we have a total of  marbles. That means that each marble, regardless of color, has a  chance of being picked, as shown in the images below. This image shows equal probability because each marble has a  chance of being drawn, which is equal to the probability of all of the other marbles.

Megan wants to know what her probability is of drawing a pink marble out of her bag. Remember, probability is the number of favorable outcomes over the total number of outcomes:

For this problem there are  pink marbles; therefore,
