Answer

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 (contacts from school) is 16, and the total number of outcomes (total contacts) is 30.

Step3: Calculate probability

$P(\text{call a person from school})=\frac{16}{30}=\frac{8}{15}\approx 0.53$

Answer:

0.53
