Question 5: (Total probability) A toy shop sells four kinds of stuffed animals (bear-B, lion-L, unicorn-U & dog- D), each available in 3 colors. (a) Write an expression for total probability that a randomly selected stuffed animal is white (one of the three colors), P(W), using n operator. Hint: sum of the probabilities each kind of stuffed animal is white. (b) Modify the expression from (a) above to use conditional probability. Hint: Use the rule P(A|B) = P(AnB) where P(B) > 0 P(B)
