Alex has two funds A and B. The annual return of fund A is
denoted by X (in %) while the annual return of fund B is denoted by
Y (in %) . Assume X ∼ U (−10, 20) and Y ∼ N (10, 50). Further,
suppose the probability that both stocks A and B have positive
annual returns is 0.6.
Find the probability that stock A has a negative return.
Find the probability that stock B has a positive...
