An experiment has the four possible mutually exclusive outcomes A, B,

1.	An experiment has the four possible mutually exclusive outcomes A, B, C and D. Check whether the following assignments of probability are permissible. P(A) = 0.32, P(B) = 0.28, P(C) = -0.06, P(D) = 0.46
Answer» Probability of an event cannot be negative. Here P(C) = – 0.06. ∴ the above set of events are not possible. P(A) = 1/3, P(B) = 1/6, P(C) = 2/9, P(D) = 5/18

Answer»

Probability of an event cannot be negative. Here P(C) = – 0.06.

∴ the above set of events are not possible.

P(A) = 1/3, P(B) = 1/6, P(C) = 2/9, P(D) = 5/18
