1. Which of the following will not be a probability function?
a) X (1,2,3,4,5) p(x) = x/15
b) X (1,2,3,4,5) p(x) = 0.2
c) X (1,2,3,4,5) p(x) = (x*x)/55
d) X (1,2,3,4,5) p(x) = (10-x)/10
I am adding one more question which i encountered in the mock test, can u tell me if uch questions are asked.
2. Event B&C are mutually exclusive & exhaustive P(B) = 0.3 & P(C) - 0.5. If probability of A given B is 0.6 and probability of A given C is 0.2, what is the unconditional probaility of A?
