StatisticsQ&A LibraryFrom a prior national study, we are able to infer that the probability of a high school student goingto college, when the parents make over $75,000 per year, is about 0.60. Assume that Toms River has125 graduating seniors next year, and all the parents are assumed to make over $75,000. If sixstudents are randomly selected, what is the probability that less than two of them will actually go tocollege?2.Question

Step 1

In this question, we have given that probability that a student going to college when parents make over $75000 is equal to 0.60. We have randomly selected 6 students whose parents make over $75000 and we have to calculate the probability that less than two will actually go to college.

Step 2

Probability less than 2 means either equal to 0 or 1. So, to get the probability we ...
