Answer: The required value is P(A ∪ B) = 0.73.
Step-by-step explanation: Given that A and B are two mutually exclusive events where
We are to find the following probability :
P(A ∪ B).
We know that
the intersection of two mutually exclusive events is null event. That is,
A ∩ B = ∅ ⇒ P(A ∩ B) = 0.
From the laws of probability, we have
Thus, the required value is P(A ∪ B) = 0.73.
