Probability: Multiple Events (Dependent and Independent) To find the probability that a 1st event happens and a 2nd event also happens, multiply the two probabilities. I. Dependent Events. When events are dependent, the second probability changes depending on what event happened first.
Two events A and B are said to be independent if they do not influence one another. More formally, this means that the occurrence of one event has no effect upon the probability of the other event.
Are A and B independent events? Why or why not? 2. If P(G) = 0.18, P(M) = 0.24 and G and M are independent, what’s the probability of G and M? 3. If P(W) = 0.61 and P(J) = 0.45 and P(J|W) = 0.2, find the following: a. P(W and J) = . b. P(W or J) = . 4. If P(Y) = 0.54 and P(L) = 0.30 and P(Y U L) = 0.678, find the following: a. P(Y ∩ L) = . b.
