Please help with these Webassign problems! Thank you :)

1. [-/5 Points] Use Bayes' theorem or a tree diagram to calculate the indicated probability. Round your answer to four decimal places. P(A | B) = 0.5, P(B) = 0.8, PM | 55 = 0.4. Find P(B |A). P(5 1 A) = 2. [-I5 Points] Use Bayes' theorem or a tree diagram to calculate the indicated probability. Round your answer to four decimal places. Y1, Y2, Y3 form a partition of s. P(X | Y1) = 0.5, P(X| Y2) = 0.2, P(X| Y3) = 0.8, P(Y1) = 0.2, P(Y2) = 0.1. Find P(Y1 | X). Pm IX) = 3. [-I5 Points] Weather Suppose that it snows in Greenland an average of once every 30 days, and when it does, glaciers have a 24% chance of growing. when it does not snow in Greenland, glaciers have only a 2% chance of growing. What is the probability that it is snowing in Greenland when glaciers are growing? (Round your answer to four decimal places.)
