<PRE><B>Question 1036314</B>
n investor invests in stocks without being informed of all the intricacies of stock market. The probability that his 1st investment in one market sector is a good stock is 1/3 and that his second investment in an unrelated market sector is a good stock is 1/4. 
Find THE probability that: 
A)At least one investment would be a good stock
P(at least one good) = 1 - P(both bad) = 1-(2/3)(3/4) = 1/2
========================================= 
B)Both the investments would be good stocks
P(both good) = 1/3 *1/4 = 1/12
-------------------------------------------
C) Only one investment would be a good stock
P(one good) = 1 - [(1/12)+(1/2)] = 1-7/12 = 5/12
------------------------------ 
D)None of the investments would be a good stock.
P(none good) = (2/3)(3/4) = 1/2
