Question 3 |
Let A and B be two arbitrary events, then :
P(A∩B) = P(A) P(B) | |
P(P∪B) = P(A) + P(B) | |
P(A∪B) ≤ P(A) + P(B) | |
P(A / B) = P(A∩B) + P(B) |
Question 3 Explanation:
Option-A is happens when A and B are independent.
Option-B is happens when A and B are mutually exclusive.
Option-C is not happens.
Option-D is P(A∪B) ≤ P(A) + P(B) is true because P(A∪B) = P(A) + P(B) – P(A∩B).
Option-B is happens when A and B are mutually exclusive.
Option-C is not happens.
Option-D is P(A∪B) ≤ P(A) + P(B) is true because P(A∪B) = P(A) + P(B) – P(A∩B).
