Find P(A or B) if the events are disjointed. P(A) =6/25 , and P(B) =9/25 .
Accepted Solution
A:
Here, "disjointed" signifiies that Event A and Event B are independent; neither outcome influences the other. In such a case, the union of A and B is given by the sum of the two probabilities P(A) and P(B).
Here, that sum is P(A or B) = 6/25 + 9/25, or 15/25, or 0.6.
