For safety reasons, 3 different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills bank. Each of the 3 systems detects theft with a probability of 0.85 independently of the others. es. The bank, obviously, is interested in the probability that when a theft occurs, at least one of the 3 systems will detect it. What is the probability that when a theft occurs, at least one of the 3 systems will detect it? Your answer should be rounded to 4 decimal places.
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?
Of the students who registered for the statistical teaching assistant, 75 percent came from the economics department, 19 percent came from the Islamic economics department, and 6 percent came from the accounting department. Students who did not pass 94 percent of the economics major, 95 percent of the Islamic economics major, and 96 percent of the accounting major, the rest were students who passed.

The route used by a certain motorist in commuting to work contains two intersections with traffic signals. The probability that he must stop at the first signal is 0.45, the analogous probability for the second signal is 0.5, and the probability that he must stop at at least one of the two signals is 0.55. (a) What is the probability that he must stop at both signals? (b) What is the probability that he must stop at the first signal but not at the second one? (c) What is the probability that he must stop at exactly one signal?
Bag 1 contains 8 gray rocks and 5 black rocks, and Bag 2 contains 9 gray rocks and 4 black rocks. Suppose we flip a fair coin. If the result is heads, we randomly select a rock from Bag 1; if the result is tails, we randomly select a rock from Bag 2. Suppose that a gray rock was selected. What is the probability that the rock came from Bag 1?
11. As a small business owner, you decide to randomly give two of your loyal customers a $100 gift card each. To decide who gets the gift cards, you write down the names of each loyal customer and draw them out of a hat. You draw two names without replacement so that one person does not get both $100 gift cards. Of the 6 loyal customers you have, 3 live in Georgia. What is the probability that both of the $100 gift cards go to a loyal customer living in Georgia? .2 O.25 O.3 O none of the above are correct

You are the teacher of two math classes of 20 and 25 students respectively. To get into a university program, the students need a 75% in the class. Suppose each student has a 0.7 probability of getting atleast a 75% in the class. Let X1 be the number of students in the class of 20 who receive atleast a 75%. Let X2 be the number of students in the class of 25 who receive atleast a 75%. a. Do X1 and X2 fit the binomial setting? Are there any issues? For the rest of the question, assume both X1 and X2 can be modeled by a binomial distri- bution. b. What is the probability that exactly 15 students in the class of 20 get into the pro- gram? Do not use Table C. c. What is the probability that atleast 22 students in the class of 25 get into the pro- gram? Do not use Table C. d. Using Table C, what is the probability that atleast 17 students in the class of 20 get into the program? е. Let X be the number of students in both classes that get into the program.
