Question

lacey is picking out fabric for her bedroom. she has 10 fabric samples, and 4 of them are checkered. what is the probability that a randomly selected fabric sample will be checkered? write your answer as a fraction or whole number. p(checkered) =

Explanation:

Step1: Recall probability formula

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

Step2: Identify values

The number of favorable outcomes (checked - fabric samples) is 4, and the total number of outcomes (total fabric samples) is 10.

Step3: Calculate probability

$P(\text{checked})=\frac{4}{10}=\frac{2}{5}$

Answer:

$\frac{2}{5}$
