Answer 1

Hello!

First, let's rewrite some important information contained in the exercise:

• 14 blue pens.

,

• 8 black pens.

,

• 6 red pens.

• Total: 28 pens.

What is the probability that the students will pick NOT a red or black pen?

Well, let's think for a moment:

If he won't pick up either black or red pens, it means he can only pick up blue pens, right?

So, we can write it as a fraction, decimal or percent:

`\frac{\text{ number of blue pens}}{\text{ total of pens}}=(14)/(28)=(1)/(2)=0.5=50\%`
