Assume that A and B are two events, and that the following probabilities are given: P(A and B) = 0.3, P(A) = 0.4, and P(B) = 0.5. Find: P(B ∩ (A ∪ B)).
Added by Sabrina M.
Step 1
This can be calculated using the formula: P(A or B) = P(A) + P(B) - P(A and B) Substituting the given values, we get: P(A or B) = 0.4 + 0.5 - 0.3 P(A or B) = 0.6 Now, we need to find the probability of B given that A or B has occurred, which is denoted as P(B Show more…

If $A, B,$ and $C$ are mutually exclusive events with $P(A)=0.2, P(B)=0.3,$ and $P(C)=0.4,$ determine the following probabilities: (a) $P(A \cup B \cup C)$ (b) $P(A \cap B \cap C)$ (c) $P(A \cap B)$ (d) $P[(A \cup B) \cap C]$ (e) $P\left(A^{\prime} \cap B^{\prime} \cap C^{\prime}\right)$
