Answer

Explanation:

Step1: Calculate total number of pens

$2 + 2+2 + 1+1+1+1=10$

Step2: Determine number of red pens

There are 2 red pens.

Step3: Calculate probability

Probability = $\frac{\text{Number of red pens}}{\text{Total number of pens}}=\frac{2}{10}=\frac{1}{5}$

Answer:

A. $\frac{2}{10}$ simplified $\frac{1}{5}$
