willow has a cup of pens on her desk. she has 2 black, 2 blue, 2 red, 1 yellow, 1 green, 1 brown and 1 orange. without looking, what is the probability of willow selecting a red pen? a $\frac{2}{10}$ simplified $\frac{1}{5}$ b $\frac{1}{10}$ c $\frac{4}{10}$ simplified $\frac{2}{5}$ d $\frac{2}{6}$ simplified $\frac{1}{3}$
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 $\frac{1}{5}$
