Final answer:
The probability of event A or B occurring, when events are inclusive and given P(A) = 0.6, P(B) = 0.4, and P(A AND B) = 0.1, is 0.9.
Step-by-step explanation:
You are asked to determine the probability of P(A OR B) given that P(A) = 0.6, P(B) = 0.4, and P(A AND B) = 0.1.
The events are inclusive, which means they are not mutually exclusive and can happen at the same time.
The formula to use for inclusive events is:
P(A OR B) = P(A) + P(B) − P(A AND B).
Plugging in the values you provided:
P(A OR B) = 0.6 + 0.4 − 0.1 = 0.9
The probability of event A or B occurring is 0.9.
