Concept explainers
Red Light/Green Light A busy street has three traffic lights in a row. These lights are not synchronized, so they run independently of each other. At any given moment, the
a. Identify the action with a random outcome, and give the probability that it is a success.
b. Explain how you will simulate this action using the random number table in Appendix
A. Which digits will represent green, and which non-green? If you want to get the same results we did, use all the possible one-digit numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9), and let the first few represent the green lights. How many and what numbers would represent green lights, and what numbers would represent nongreen lights?
c. Describe the
d. Explain how you will simulate a single trial.
e. Carry out 20 repetitions of your trial, beginning with the first digit on line 11 of the random number table. For each trial, list the random digits, the outcomes they represent, and whether or not the event of interest happened.
f. What is the empirical probability that you get three green lights?

- On a game show, a contestant is given the digits 3, 4, and 5 to arrange in the proper order to form the price of an appliance. If the contestant is correct, he or she wins the appliance. What is the probability of winning when the contestant knows that the price is at least $400?arrow_forwardDetermine if the statement is true or false. If the statement is false, then correct it and make it true. The probability that an event occurs can be a negative number.arrow_forwardFind the probability of each event.

- Determine if the statement is true or false. If the statement is false, then correct it and make it true. The probability of a couple having four boys is 12 because the probability each time of having a boy is 12.arrow_forwardIf the spinner shown below is spun, find the probability of each event. Assume that the spinner never stops on a line. The spinner stops on orange.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. Find the probability that all engines will survive the test.arrow_forward
