H13 #3 An experiment is given together with an event. Find the (modeled) probability of each event, assuming that the coins are distinguishable and fair, and that what  is observed are the faces uppermost. (Compare with Exercises 1-10 in Section 7.1.) Three  coins are tossed; the result is at most one  head . 1/8+3/8=1/2 #4 An experiment is given together with an event. Find the (modeled) probability of each event, assuming that the dice are distinguishable and fair, and that what  is observed are the numbers uppermost. (Compare with Exercises 1-10 in Section 7.1.) Two dice are rolled; the numbers add to  3 . 1/18 #7 Use the given information to find the indicated probability. HINT [See Quick Examples, page 476.] P ( A     B ) =  .9 P ( B ) =  .6

Unformatted text preview: P ( A ∩ B ) = .5 . Find P ( A ). 0.8 H14 Compute the indicated quantity. P ( A | B ) = .2 , P ( B ) = .5 . Find P ( A ∩ B ). P ( A ∩ B ) =0.1 H15 #7 The Sorry State Lottery requires you to select five different numbers from 0 through 42 . (Order is not important.) You are a Big Winner if the five numbers you select agree with those in the drawing, and you are a Small-Fry Winner if four of your five numbers agree with those in the drawing. (Enter your answers as exact answers.) What is the probability of being a Big Winner? What is the probability of being a Small-Fry Winner? What is the probability that you are either a Big Winner or a Small-Fry Winner?...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
