he graph shows the number of each kind of cd in dantes collection. what is the probability that a randomly chosen cd will be country? types of music cds rock 8 country 12 pop 10 hip - hop 8 15% 20% 25% 30%

Explanation:

Step1: Calculate total number of CDs

Total CDs = \(8 + 12+10 + 4+8=42\)

Step2: Use probability formula

Probability \(P=\frac{\text{Number of Country CDs}}{\text{Total CDs}}\)
Number of Country CDs \(= 12\), Total CDs \(= 40\)
\(P=\frac{12}{40}=\frac{3}{10}=0.3 = 30\%\)

Answer:

30%
