The probability of a and b

The probability of A or B depends on if you have mutually exclusive events (ones that cannot happen at the same time) or not. If two events A and B are mutually exclusive, the events are called disjoint events. The probability of two … Visa mer The probability of A and B means that we want to know the probability of two events happening at the same time.

WebbThe present work considers a left-continuous random walk moving on the positive integers and having an absorbing state at the origin. Limit theorems are derived for the position of the walk at time n given: (a) absorption does not occur until after n, or (b) absorption does not occur until after m + n where m is very large, or (c) absorption occurs at m + n.

WebbTheorem 8.3: If A and B are two events in an experiment such that A ⊂B, then P (B-A) = P (B) – P (A). Proof: It is given that A ⊂ B. The event B can be expressed as B = A ∪ (B-A) (see Figure 8.6) Since A ∩(B-A) = φ, P (B) = P (A ∪ (B-A)) Hence, by Axiom-3, => P (B) = P (A) + P (B-A) Therefore, P (B-A) = P (B) – P (A).
