2. Let C = cloudy. S = sprinkler, R = rain, and W = wet grass. Use the Bayesian Network described below with P(C) = 0.5 to calculate the probability of it raining given the grass is wet. Calculate the probability of the sprinkler being on given the grass is wet. (Note: to change into randora variables let F=0 and T=1.
