Consider a well-mixed urn with 50 red balls, 30 blue balls, and 20 yellow balls, along with a standard, well-shuffled deck of cards (jokers excluded). Consider the following events: A = {a red or blue ball is drawn}, B = {a yellow or red ball is drawn}, C = {a 7 is drawn}, D = {a card with number less than or equal to 7 is drawn}, E = {a card with number great than or equal to 7 is drawn}. Note: Ace is high; balls and cards are drawn separately and are not mixed together. (a) Suppose that a single card and a single ball is drawn. Calculate the following. i. p(A), P(B). P(C), P(D), P(E). ii. p(B and C), p(D and E) iii. p( A or C), p( D or E) iv. p(A|B), P(D E)
