network number of people
abc 80
cbs 35
nbc 60
fox 35
msnbc 40
determine the empirical probability that the next person randomly selected from the town watches abc news.

Explanation:

Step1: Recall empirical - probability formula

Empirical probability $P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify favorable and total outcomes

The number of people who watch ABC news is 80 (favorable outcomes), and the total number of people surveyed is 250 (total number of outcomes).

Step3: Calculate the probability

$P(\text{watches ABC news})=\frac{80}{250}=\frac{8}{25} = 0.32$

Answer:

$0.32$
