In a certain college, 33% of the physics majors belong to ethnic minorities. Find the probability of the event that, from a random sample of 10 students who are physics majors, 2 or less belong to an ethnic minority.
Compute the probability that 2, 1, and 0 are minorities out of the ten, and add those probabilities.
The probability that 0 are minorities ...
This shows how to find the probability of a certain population situation.
