The probability that a company will launch the product A and B are 0.45 and 0.60 respectively,
highlight%28in_main_while%29 ( ? ), probability that both products launched, is 0.35. what is the probability that

(1) Neither will of these products launch ?
(2) At least one product will be launched?
~~~~~~~~~~~~~ 


(2)  P(at least one) = P(A U B) = P(A) + P(B) - P(A ∩ B) = 0.45 + 0.6 - 0.35 = 0.7.           ANSWER 



(1)  P(Neither) = the COMPLEMENT to P(at least one) = 1 - P(at least one) = 1 - 0.7 = 0.3.    ANSWER

Solved.
