Question 664428
Only post *one* problem at a time please.


17. If events A and B are complementary events, each with non-zero probability, then
<font color="red">a. and are mutually exclusive</font>
b. A and B are independent
c. both (a) and (b)
d. neither (a) nor (b) 


This is because if A and B are complementary, then P(A) + P(B) = 1, which implies they are mutually exclusive.
