WebbWe note that this process leads to the standard formula 𝑃 ( 𝐴 ∣ 𝐵) = 𝑃 ( 𝐴 ∩ 𝐵) 𝑃 ( 𝐵), where 𝑃 ( 𝐴 ∣ 𝐵) is the conditional probability of event 𝐴 given another event 𝐵. We can also use a Venn diagram to describe relationships between three events. WebbA probability is a chance of prediction. When we assume that, let’s say, x be the chances of happening an event then at the same time (1-x) are the chances for “not happening” of an event. Similarly, if the probability of an event occurring is “a” and an independent probability is “b”, then the probability of both the event occurring is “ab”.
WebbSimply note that P ( A) = P ( A ∩ B) + P ( A ∩ B c), since A ∩ B and A ∩ B c are mutually exclusive events, and their union is A. Hence, P ( A) − P ( A ∩ B) = 0.7 is the answer. … WebbFind the probability that a randomly selected patient has the disease and tests positive. Use tree diagram to present the given information b.
