WebQuestion 367064: If P (A or B) = 0.7, P (A) = 0.3 and P (B) = 0.8, determine. P (A and B). Answer by Jk22 (389) ( Show Source ): You can put this solution on YOUR website! The relationship is : P (A or B) = P (A) + P (B) - P (A and B) here : .7 = .3 + .8 - P (A and B) => P (A and B) = 1.1 - 0.7 = 0.4. WebApr 17, 2024 · Suppose we have two independent events whose probability are the following: P ( A) = 0.4 and P ( B) = 0.7. We are asked to find P ( A ∩ B) from probability theory. I know that P ( A ∪ B) = P ( A) + P ( B) − P ( A ∩ B). But surely the last one is equal zero so it means that result should be P ( A) + P ( B) but it is more than 1 (To be ...

WebTo find: The probability of getting a 2 or 3 when a die is rolled. Let A and B be the events of getting a 2 and getting a 3 when a die is rolled. Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0. Using the P (A∪B) formula, WebP (A ∪ B) = P (A) + P (B) A six-sided die is tossed 3 times. The probability of observing three ones in a row is. 1/216. The probability of the occurrence of event A in an experiment is 1/3. If the experiment is performed 2 times and event A …
WebQuestion: Assume that P (A) = 0.3, P (B) = 0.7 Can you compute P (A and B) if you only know P (A) and P (B)? Assuming that events A and B arise from independent random processes, what is P (A and B)? what is P (A or B)? what is P (A B)? It we are given that P (A and B) = 0.1, are the random variables giving rise to events A and B independent? WebP (A ∩ B) = P (A) × P (B A) = (3/10) × (7/9) = 0.2333 Union of A and B In probability, the union of events, P (A U B), essentially involves the condition where any or all of the events being considered occur, shown in the Venn diagram below. Note that P (A U B) can also be written as P (A OR B). In this case, the "inclusive OR" is being used.

Rearranging this last equation as P(AB)/P(A)=P(B), we see that if P(A B)=P(A), then also P(B A)=P(B).
