bixtya [17]

Answer:

There is a 50% probability that at least one roommate is doing homework this Friday night.

Step-by-step explanation:

This problem can be solved building the Venn Diagram of these probabilities.

I am going to say that P(A) is the probability that the roommate A is doing homework and P(B) is the probability that the roommate B is doing homework.

We have that:

$P(A) = P(a) + P(A \cap B)$

In which P(a) is the probability that only the roommate A is doing homework and $P(A \cap B)$ is the probability that both student A and student B are doing homework.
