Answer:
0
Step-by-step explanation:
Given that:
The probability of event A = 0.4
i.e. P(A) = 0.4
The probability of event B = 0.5
P(B) = 0.5
Given that A and B are disjoint, then they do not have any elements in common. Thus, the probability that both events will occur is;
P(A ∩ B) = empty set {}, and the cardinality of the intersection of these two disjoint sets are, therefore, zero (0).
