1. In light of the COVID-19 situation in the US, the chance any one of the 27 Jesuit Consortium Colleges opening for fall 2020 semester with on-site student presence on campus is 15%. Father Luige Mario, who is in charge of campus readiness this year, is trying to determine how many campuses, if any, will be ready.

Answer #1

(a) The Distribution used will be the Binomial Distribution as there are only 2 outcomes, opening or not opening. The number of trials are fixed and independent of each other, and the sample taken is a simple random sample.

Binomial Probability = nCx * (p)x * (q)n-x, where n = number of trials and x is the number of successes.

_________________________

(b) Expectation = Mean = n * p = 27 * 0.15 = 4.05

____________________________

(c) Variance = n * p * (1 - p) = 27 * 0.15 * 0.85 = 3.4425

___________________________

(d) P(X = 27) = 27C27 * (0.15)27 * (0.85)27-27 = 0.000
