Question

a box contains 20 crayons. there are 2 yellow, 4 blue, 6 red, and 8 orange crayons. without looking, luisa reaches into the box and picks one crayon. what is the probability that the crayon is blue? a $\frac{2}{5}$ b $\frac{3}{10}$ c $\frac{1}{5}$ d $\frac{1}{10}$

Explanation:

Step1: Recall probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify favorable and total outcomes

The total number of crayons is 20. The number of blue crayons (favorable outcomes) is 4.

Step3: Calculate the probability

$P(\text{blue})=\frac{4}{20}=\frac{1}{5}$

Answer:

C. $\frac{1}{5}$
