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.
Proportional... 4/5 so are there more red or green, you need to answer that question first, then you can line up that answer with how many there are and butterfly it. Ex:
4/5. 4 red to 1 green
