Answer:
Probability is the chances of an event occurring or not occurring in an experiment.
Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.
Explanation:
P(Exactly 26 undergraduates will earn a degree) = P(26);
P(Sample of Students) = P(200);
P(11% of American students earn a degree) = P(11% or 0.11)
∴ The probability that exactly 26 undergraduate earning a degree = P(200)/P(26) = 7.69
∴ To find the 11% of the American College students that earn a degree =
7.969 x 0.11 = 0.8459≅ 0.9
