Question

1. phones of 45 people who purchase a phone at an electronics store, 40 purchased a smartphone. determine the empirical probability that the next person who purchases a phone from that store purchases a smartphone.

Explanation:

Step1: Recall probability formula

The empirical - probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify values

The total number of people who purchased a phone is $n = 45$, and the number of people who purchased a smartphone is $m = 40$.

Step3: Calculate probability

$P=\frac{m}{n}=\frac{40}{45}=\frac{8}{9}$.

Answer:

$\frac{8}{9}$
