Question

In a science class of twenty-eight students. 12 boys and girls. On a unit test, 4 boys and 10 girls made an A grade. A student is chosen at random from the class. What is the probability of choosing a boy or an A student?

Answer 1

Answer:

Step-by-step explanation:

probability of choosing a boy = 12 / 28 = 3 / 7

in % = 3 / 7 x 100 = 42,86%

probability of choosing an a student = (4 + 10) / 28 = 14 / 28 = 1 / 2

in % = 1 / 2 x 100 = 50%
