Find the probability that either event A or B occurs if the chance of A occurring is 0.5,the chances of B occurring is 0.3, and events A and B are independent.

Suppose a free throw shooter makes 67 percent of their first attempts.  On the second attempt they make 81 percent if they had made their first attempt, but 59 percent if they had miss.  What is the probability that they make one of two attempts (one or the other attempt, but not both)?

If there is a 10% chance it will rain each day for the next week, what is the probability that it will rain at least once?

Andrea did a survey in her statistics class and found that 18 students out of 25 use the library at least twice a week.    What is the probability that a student chosen at random from the class uses the library at least twice a week? What is the probability that a student chosen at random from the class uses the library less often than twice a week? If two students are chosen at random from the class, what is the probability that both of them use the library at least twice a week? If two students are chosen at random from the class, what is the probability that both of them do NOT use the library at least twice a week?

Consider the situation that two events A and B are independent. P(A) = 0.2 and P(B)= 0.5. What is the probability that both events A and B occur?

2. The probability that it will rain today is 50%. The probability that it will rain tomorrow is 60%. There is a 30% probability that it will rain both days. What is the probability that it will rain either today or tomorrow?

Suppose the probability that you will be elected student president is 0.15, and the probability that you will get the student scholarship is 0.55. If the two events are independent, the probability that you will not only become the  president but also get the scholarship is:  need complete solution

If the probability of an event E is 2/3​, then the probability that E will not occur is

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first period class on time is 0.37.  The probability that Napoleon and Pedro catch the bus is 0.66. However, the probability that they make it to their first period class on time, given that they catch the bus is 0.61.  What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time?

10:31 K A baseball player hit 61 home runs in a season. Of the 61 home runs, 24 went to right field, 17 went to right center field, 11 went to center field, 8 went to left center field, and 1 went to left field. (a) What is the probability that a randomly selected home run was hit to right field? (b) What is the probability that a randomly selected home run was hit to left field? (c) Was it unusual for this player to hit a home run to left field? Explain. (a) The probability that a randomly selected home run was hit to right field is (Round to three decimal places as needed.) ||| = Vo) 1 LTE 4G 5% O
