Events A and B are given such that P(A)=7/10, P(A U B)=9/10 and P(A bigcap (upside down U) B)=3/10.

Find P(B) and P(B' bigcap (upside down U) A)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
