has a visa credit card and b be the analogous event for a mastercard. suppose that , p(a)= 0.6 and p(b)=0.4.
a. could it be the case that p( a ∩ b )=0.5, why or why not?
b. from now on, suppose that p( a ∩ b )=0.3 what is the probability that student has one of these two types of cards?
c. what is the probability that the selected student has neither type of card?
