Assume that A, B, and C are events. It is true that A and B are independent, and A and C are disjoint (incompatible). In addition, P(A) = 0.45, P(B) = 0.50, and P(A∪B∪C) = 0.8. Calculate P(A∪B).

Step 1
First, we know that A and B are independent, so we can use the formula: P(A∩B) = P(A) × P(B) We also know that A and C are disjoint, so they have no common outcomes. Show more…

Let A and B be two events with P(A) = 0.13, P(B) = 0.04, and P(A ∪ B) = 0.1323. Then, A and B are disjoint and not independent.

- Let a and b be two disjoint events with P(a) = 0.34 and P(b) = 0.38. What is P(A and B)? - Let a and b be two independent events with P(a) = 0.18 and P(b) = 0.74. What is P(A and B)? - Let a and b be two disjoint events such that P(a) = 0.24 and P(b) = 0.44. What is P(a or b)? - Let a and b be two independent events. If P(A) = 0.71 and P(B) = 0.22, what is P(A | B)?
