Chapter 6.2, Problem 21E

College Applications The table that follows was derived from a survey of college freshmen in 2015. Each probability is the likelihood that a randomly selected freshman applied to the specified number of colleges. For instance, 10% of the freshmen applied to just one college, and therefore, the probability that a student selected at random applied to just one college is .10.

a. Convert these data into a probability distribution with outcomes 1, 2, 3, 4, and $\ge 5$.

b. What is the probability that a student applied to three or more colleges?

Number of Colleges Applied To	Probability
1	.10
2 or fewer	.17
3 or fewer	.27
4 or fewer	.40
20 or fewer	1
