If a laptop is picked at random;
(1) What is the possibility that it is (Type B) And (in the High price category)?
(2) What is the possibility that is type A given that it is not High Priced?
(3) What is the likelihood that it is Type A or High Priced?
(4) 2 laptops are selected at random without replacement, what is the probability that both are high priced?
