Question

Among the 7th graders, 50% of the students pass their math class and 50% of the students pass their science class.

What is the probability that Andre, a 7th grade student, passes both his math and science class?

Answer 1

Explanation:

the combination of two 50% events (= 1/2 = 0.5) is the product of both probabilities.

the probabilty that Andre passes both is

0.5 × 0.5 = 0.25 = 1/4 = 25%
