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 ( 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
