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

(a) the probability that two or more independent events will both occur,

(b) the probability that two or more independent events will both occur in the offspring of one set of parents

(c) the probability that either one of two independent events will occur

(d) the probability of producing two or more heterozygous offspring

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.
