![Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card and B be the analogous event for Mast
Suppose that P(A) = 0.7 and P(B) = 0.4.
(a) Could it be the case that P(A N B) = 0.5? Why or why not? [Hint: For any two sets A and B if A is a subset of B then P(A) S P(B).]
O Yes, this is possible. Since B is contained in the event AN B, it must be the case that P(B) S P(A N B) and
0.5 > 0.4 does not violate this requirement.
O Yes, this is possible. Since AN B is contained in the event B, it must be the case that P(B) S P(A N B) and
0.5 > 0.4 does not violate this requirement.
O No, this is not possible. Since B is contained in the event ANB, it must be the case that P(A N B) S P(B). However
0.5 > 0.4 violates this requirement.
O No, this is not possible. Since B is equal to AN B, it must be the case that P(A N B) = P(B). However 0,5 > 0.4 violates this reguirement.
