Answer

Explanation:

Step1: Calculate total number of singers

$5 + 22+8 + 5=40$

Step2: Calculate probability of selecting a soprano

The number of sopranos is 5. Probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{soprano})=\frac{5}{40}=\frac{1}{8}$

Answer:

$\frac{1}{8}$
