In Exercises 1–22, use Bayes’ theorem to calculate the probabilities.
Scholarship Winners Twenty percent of the contestants in a scholarship competition come from Pylesville High School, 40% come from Millerville High School, and the remainder come from Lakeside High School. Two percent of the Pylesville students are among the scholarship winners; 3% of the Millerville contestants and 5% of the Lakeside contestants win.
a. If a winner is chosen at random, what is the probability that they are from Lakeside?
b. What percentage of the winners are from Pylesville?

- In a town with 5000 adults, a sample of 50 is selected using SRSWOR and asked their opinion of a proposed municipal project; 30 are found to favor it and 20 oppose it. If, in fact, the adults of the town were equally divided on the proposal, what would be the probability of observing what has been observed? Approximate using the Binomial distribution. Compare this with the exact probability which is 0.0418.arrow_forward1.2.19. Let and s be natural numbers. Let G be the simple graph with vertex set Vo...
