Consider randomly selecting a student at a certain university, and let A denote the event that the selected individual has a Visa credit card and B be the analogous event for a MasterCard. Suppose that P(A) = 0.6, P(B) = 0.5, and P(A n B) = 0.15.
(a) Compute the probability that the selected individual has at least one of the two types of cards (i. e., the probability of the event A ? B).
(b) What is the probability that the selected individual has neither type of card?
c) Describe, in terms of A and B, the event that the selected student has a Visa card but not a MasterCard.
A' n B
A' n B'
A' ? B'
A ? B'
A n B'
Calculate the probability of this event.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
