In urn A, there are four red balls and two white balls, while urn B contains two red balls and four white balls. We throw, only once, a coin for which the probability of "tails" is equal to p (0

(a) What is the probability of obtaining a red ball on any draw?

(b) If we obtained a red ball on each of the first two draws, what is the probability of obtaining a red ball on the third draw?

(c) If we obtained a red ball on each of the first n draws, what is the probability that we are using urn A?
