Question

carsons book collection contains 12 books, including 3 mysteries. if carson randomly selects a book to read, what is the probability that it will be a mystery? write your answer as a fraction or whole number. p(mystery) =

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 number of favorable outcomes (mystery books) is 3, and the total number of outcomes (total books) is 12.

Step3: Calculate probability

$P(\text{mystery})=\frac{3}{12}=\frac{1}{4}$

Answer:

$\frac{1}{4}$
