Two events a and b are such that p(a) = 0.4, p(b) = 0.5, and p(a ∪ b) = 0.7. find the conditional probability that a randomly chosen person from this population will contract both diseases, given that he or she has contracted at least one disease. (round your answer to four decimal places.)

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
