Q:
# The two-way table shows the results of a recent study on the effectiveness of the flu vaccine.What is the probability that a randomly selected person who tested positive for the flu is vaccinated?

Accepted Solution

A:

49 %

465 + 485 = 950

465/950 = .489

.489 * 100 = 48.9, round up for 49 to get 49%, since it's only focused on people who tested positive, you would only have to compare the people in that column
