Question

Which of the following iſ the best statement of the use of the addition rule of probability?

Answer 1

Answer:

Option C

Step-by-step explanation:

Addition theory of probability is used to determine the probability for union of two or more sets.

P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.

P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)

for 3 sets

This can be extended to any number of sets

So addition theory has nothing to do with independent events both occurring

Option c is the right answer.
