Question

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?

Answer

In this problem we have a total of marbles. That means that each marble, regardless of color, has a $\frac{1}{16}$ chance of being picked, as shown in the images below. This image shows equal probability because each marble has a $\frac{1}{16}$ 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:

$\textup{P}=\frac{\textup{favorable outcomes}}{\textup{total outcomes}}$

For this problem there are pink marbles; therefore,

$\textup{P(pink marble)}=\frac{5}{16}$
