According to the rules of probability, the relationship between two dependent events is expressed in the following equation below
P(A|B) = P(A∩B) / P(B)
Substituting,
0.25 = P(A∩B) / 0.8
P(A∩B) = 0.2

The answer hence is 0.2

Suppose A and B are dependent events. If P(A|B) = 0.25 and P(B) = 0.8 , what is P(AuB)?
