The report “TV Drama/Comedy Viewers and Health Information” (cdc.gov/healthcommunication/
One question on the survey asked respondents if they had learned something new about a health issue or disease from a TV show in the previous 6 months. Data from the survey was used to estimate the following probabilities, where
L =
and
F = event that a randomly selected adult American is female
P(L) = 0.58 P(L ∩ F) = 0.31
Assume that P(F) = 0.5. Are the events L and F independent events? Use probabilities to justify your answer.
