Answer

Explanation:

Step1: Calculate total number of singers

$2 + 9+20 + 14=45$

Step2: Calculate probability of selecting a soprano

The number of sopranos is 9. Probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{soprano})=\frac{9}{45}$

Answer:

$\frac{9}{45}$
