Let S be the event that randomly selected college student has taken a statistics course and let C be the event that the same student has taken calculus 1 course. Suppose P(S) = 0.4, P(C) = 0.3 and P(S and C) = 0.2. Find the probability that a student has taken at neither statistics nor calculus.Let S be the event that randomly selected college student has taken a statistics course and let C be the event that the same student has...
Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B be the analogous event for MasterCard, and let C be the event that the selected student has an American Express card.

5. Let y|μ ~ N(μ, φ), where φ is known. There is no reliable prior information about the mean other than that it is expected to be a positive quantity. Therefore, use the improper prior distribution: p(p)-1 if (0,x) and 0 otherwise. Suppose we observe one y. Then, find the posterior mean of p. (obtain an explicit expression)
