(If necessary, consult a list of formulas.) 0 5 ?Ī university class has 22 students: 3 are psychology majors, 9 are nursing majors, and 10 are business majors. What is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory? Do not round your answer. Suppose that one piston from Machine 1 and one piston from Machine 2 are chosen at random from today's batch. Machine 2 produced 250 satisfactory pistons and 250 unsatisfactory pistons today. a 3 4 Event C: An even number on the first roll or the third roll (or both) G a 1 4Īt a factory that produces pistons for cars, Machine 1 produced 195 satisfactory pistons and 195 unsatisfactory pistons today.
1 4 Event B: An even number on both the first and the last rolls 1. Outcomes Probability DD EEO OEE EOE 000 OEO OOE EOO EEE х 2 ? Event A: No odd numbers on the first two rolls 0. Then, in the last column, enter the probability of the event. For each of the three events in the table, check the outcome(s) that are contained in the event. Note that each outcome has the same probability. The 8 outcomes are listed in the table below. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll). The experimental probability will never be very close to the theoretical probability, no matter the number of spins.Ī number cube is rolled three times. The smaller the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. The larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. (c) Assuming that the spinner is fair, choose the statement below that is true. х $ (a) From Lena's results, compute the experimental probability of landing on yellow, 0 (b) Assuming that the spinner is fair, compute the theoretical probability of landing on yellow. Round your answers to the nearest thousandths. Lena spun the dial 1000 times and got the following results, Outcome Red Yellow Blue Number of Spins 399 394 207 Answer the following. A spinner with 10 equally sized slices has 4 red slices, 4 yellow slices, and 2 blue slices.
