The route used by a certain motorist in commuting towork contains two intersections with traffic signals. The probability that he must stop at the first signal is .4, theanalogous probability for the second signal is .5, and theprobability that he must stop at at least one of the twosignals is .7. What is the probability that he must stopa. At both signals?b. At the first signal but not at the second one?c. At exactly one signal?

Jay-Z has applied to both The School of Hard Knocks and The University of OG's. He thinks the probability that The School of Hard Knocks will admit him is 0.4, the probability that The University of OG's will admit him is 0.5, and the probability that both will admit him is 0.2. Creating a Venn Diagram is Helpful. What is the probability that Jay-Z gets into The School of Hard Knocks but not The University of OGʻs?

How can I answer this question 22 ?

Given the probability that "she's up all night 'til the sun" is 0.39, the probability that "she's up all night for good fun" is 0.30, and the probability that "she's up all night 'til the sun" AND "she's up all night for good fun" is 0.18, what's the probability that "she's up all night 'til the sun" OR "she's up all night for good fun"? Round to 2 decimal places as needed.

Each of the questions in this boxpertains to rollinga pair of fair dice. Find the probability that the sum is less than 5 and the sum is prime.

suppose that an airline has two flights each day from Toronto to Winnipeg; one scheduled at 9am and the other at 3pm. On any given day, the probability that the 9am flight departs on time is .81the probability that the 3pm flight departs on time is .68. The probability that neither depart on time is .21. Find the probability that the 3p flight does not depart on time. Find the probability that both flights depart on time. Find the probability that exactly one of the two flights depart on time. Full explanation (not too complicated) would be awesome

John is having a dinner at a restaurant, which sells 3 kinds of dishes, A, B, and C. The probabilities of ordering each dish are 0.4, 0.3, and 0.3. Suppose the probability of John being satisfied after eating the dishes are 0.7, 0.5, and 0.6, respectively. Answer the questions below. 1) When John wasn’t satisfied with his dish, what is the probability that he has eaten the dish B? (Round an answer to two decimal places.)   2) What is the probability that John satisfies after eating the dish?
