Answer:
42%
Explanation:
Table attached.
In probability, "OR" means "ADDITION" and "AND" means "MULTIPLICATION".
The table gives each genre of movies and their respective probabilities.
We want probability a movie chosen at random is THRILLER "OR" COMEDY.
So we need probability of thriller and probability of comedy. And then there is "OR" between them, which means we will add the individual probabilities.
From table,
Probability of Thriller = 0.14
Probability of Comedy = 0.28
Hence
Probabilty of Thriller OR Comedy = 0.14 + 0.28 = 0.42
Converting to percentage by multiplying by 100, we get:
0.42 * 100 = 42%
