Question

Turica bas 4 different pen colors. Red, Purple, Blue, and Green. She has 8 lens of each color. She selects a pen at random. What is the probability she. select a green pen.

Answer 1

The probability of an event happening is the number of desired outcomes divided by the number of all the possible outcomes. In this case we know that Turica selected a pen. There are 4 different colors, each of these colors has 8 pens. So the total number of pens is:

$\text{total = 4}\cdot8=32$

There are 32 possible pens that Turica can select. From these she wants to select a green pen, there are 8 green pens, therefore the probability is:

$p=\frac{8}{32}=\frac{1}{4}=0.25$

The probability of selecting the Green pen at random is 0.25 or 25%.
