1.1 Verizon 8:20 PM 7.1 points MintsoStat9 4.E.507.XP My Notes An ancient Korean drinking game involves a 14-sided die. The players roll the die in tum and must submit to whatever humiliation is written on the up-face: something like "Keep still when tickled on face." Six of the 14 faces are squares. Let's call them A, B, C, D, E, and F for short. The other eight faces are triangles, which we will call 1, 2, 3, 4, 5,6,7,and 8. Each of the squares is equally likely. Each of the triangles is aso equally likely, but the triangle probabilty differs from the square probability. The probability of getting a square is 0.73. Give the probability model for the 14 possible outcomes. (Round your answers to three decimal places any one square)- any one triangle) 1/1 points I Previous Answers MintroStat9 4.E.508xP My Notes Ask Your The College Board finds that the distribution of students' SAT scores depends on the level of education their parents have.

In the old days, slot machines were like this: you pul the lever to spin three wheels; each wheel has 20 symbols, all equally likely to show when the wheel stops spinning; the three wheels are independent of each other, Suppose that the middle wheel has 11 bells among its 20 symbols, and the left and right wheels have 1 bell each. (a) You win the jackpot if all three wheels show bells. What is the probability of winning the jackpot?

Randomized response is an effective way to guarantee anonymity while collecting information on topics such as student cheating or sexual behavior. Here is the idea. To ask a sample of students whether they have plagiarized a term paper while in college, have each student toss a coin in private. If the coin lands heads and they have not plagliarized, they are to

Explanation / Answer

here let probability of traingle =a and that of square =b

hence 8a+6b =1

and 6b =0.73

theefore 8a =1-0.73 =0.27

P(any one square) =0.73/6 =0.122

P(any one traingle =0.27/8 =0.034
