- If a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)arrow_forwardAssume that the probability that an airplane engine will fail during a torture test is 12and that the aircraft in question has 4 engines. Construct a sample space for the torture test. Use S for survive and F for fail.arrow_forwardThe conditional probability of E given that F occurs is P(EF)=___________. So in rolling a die the conditional probability of the event E, getting a six, given that the event F, getting an even number, has occurred is P(EF)=___________.arrow_forward
- Assume that the probability that an airplane engine will fail during a torture test is 12and that the aircraft in question has 4 engines. Find the probability that all engines will survive the test.arrow_forwardWhen rolling two fair six-sided dice, getting a pair of 1s is called “snake eyes.” The probability of getting “snake eyes” on any roll is 1/36. Suppose that a game player rolls the two dice 80 times. Let X = the number of rolls that result in “snake eyes.” Find P(X = 2). Interpret this value in context.arrow_forwardTEST B. Solve the following. Show your solutions. 1.) Shown below is the probability distribution of X = the number of students utilizing the computer laboratory per day. X = 6 | 8 | 10 | 12 | 14 | P(x) = 1/6 | 1/6 | 1/6 | 1/6 | 1/6 | 1.a.) Give the probability that at least 12 students are using the laboratory in a given day.arrow_forward
- %A. l. https://docs.google.com/fo YO 4.4 O 3.96 O 1.8 نقطة واحدة Let X denote the number of colleges where you will apply after your results and P(X =x) denotes your probability of getting admission in x number of colleges. It is given that if x = 0 or 1 if x = 2 if x 3 or 4 otherwise kx, 2kx, P(X = x) 3= %3D k(5 - x), 0, Where k is a positive constant. Then the probability that you will get admission in at most 2 colleges is 0.625arrow_forwardHere is a few scenarios where I want you to describe how you would set up either binomialcdf or binomialpdf on your calculators. Use correct probability notation (ex P(X = 3) = .1314), and for the inequalities give a brief example of which values for X you are trying to "include" in your calculation, and the logic behind why you are setting up your calculator function in a given way. A Multiple Choice test is given consisting of 10 questions, each question having 5 possible answers, one of which is correct. Jimmy hasn't studied and prepared himself for the test, and is therefore forced to completely guess on each question. Find the probability that: (1) He gets exactly 5 (half) of the questions correct (2) He gets ALL the questions correct (3) He gets NONE of the questions correct (4) He gets at least a 60% (passing) on the test. (5) He gets at most 5 correct.arrow_forwardMany professional baseball teams (including the Cincinnati Reds and the Boston Red Sox) use Bill James's formula to estimate their probability of winning a league pennant: (Runs scored)2 (Runs scored)2 + (Runs allowed)2 Probability) of winning This formula, whose form is reminiscent of the Pythagorean theorem, is considered more accurate than just the proportion of games won because it takes into consideration the scores of the games.t Find this probability for a team that has scored 500 runs and allowed 400 runs. (Round your answer to the nearest whole percent.)arrow_forward
- 2. Consider the function fxy (x,y)=c(x² +y² ), a joint probability density function over 0arrow_forward) If the probability of a person getting a job is x / 3 The probability of not getting a job is 2/3 . So what is the value of xarrow_forwardA student goes to the library. Let events B = the student checks out a book and D = the student checks out a DVD. Suppose that P(B) = 0.56, P(D) = 0.95 and P(B AND D) = 0.39. Find P(D|B). Give your answer as a decimal rounded to the nearest hundredth.arrow_forwardarrow_back_iosarrow_forward_ios
