Based on previous records,17% of the vehicles passing through a tollbooth have out-of-state plates. A bored tollbooth worker decides to pass the time by counting how many vehicles pass through until he sees two with out-of-state plates.27

(a) Describe the design of a simulation to estimate the average number of vehicles it takes to find two with out of- state plates. Explain clearly how you will use the partial table of random digits below to carry out your simulation.

(b) Perform three repetitions of the simulation you described in part (a). Copy the random digits below onto your paper. Then mark on or directly above the table to show your results.

Short Answer

Expert verified

Part (a) We'll run the simulation several times to figure out the average time.

Part (b) Three numbers were needed and the time is 13

Step by step solution

01

Part (a) Step 1. Given

Out-of-state plates are found on17% of vehicles passing through a tollbooth. A bored tollbooth worker kills time by counting the number of automobiles passing through until he notices two with out-of-state plates.

02

Part (a) Step 2. Explanation

According to previous figures, 17% of vehicles travelling through a tollbooth have out-of-state plates in the question. As a result, we'll employ two-digit numbers. Then we'll pick a row from table D. After that, choose the first two-digit number. If the number is between 00 and 16, a car with out-of-state plates has passed through the toll booth; otherwise, disregard the number. Then we'll do it all over again until you get the first number between 00 and 16. We'll repeat this process until you get the second number between 00 and 16. As a result, the time is the number of digits required to get two numbers between 00 and 16. As a result, we'll run the simulation numerous times and average the results.

Part (b) Step 1. Explanation

According to previous figures, 17%of vehicles travelling through a tollbooth have out-of-state plates in the question. As a result, we'll employ two-digit numbers. Then we'll pick a row from table D. After that, choose the first two-digit number. If the number is between 00and 16, a car with out-of-state plates has passed through the toll booth; otherwise, disregard the number. Then we'll do it again until you get the first number between00and 16. We'll repeat this process until you get the second number between 00and 16. As a result, the time is the number of numbers required to achieve two numbers between 00 and 16 until the second number between 00and 16is received. As a result, the first simulation will take place.

As a result, three integers were required, and the time was calculated. The second simulation will be as follows:

As a result, three numbers were required, and the time was 13 minutes.

A Titanic disaster In 1912the luxury liner Titanic, on its first voyage across the Atlantic, struck an iceberg and sank. Some passengers got off the ship in lifeboats, but many died. The two-way table gives information about adult passengers who lived and who died, by class of travel. Suppose we choose an adult passenger at random.

(a) Given that the person selected was in first class, what鈥檚 the probability that he or she survived?

(b) If the person selected survived, what鈥檚 the probability that he or she was a third-class passenger?

Roulette, An American roulette wheel has38slots with numbers 1through 36,0,and00,as shown in the figure. Of the numbered slots, 18are red, 18are black, and 2鈥攖丑别 0and 00鈥攁re green. When the wheel is spun, a metal ball is dropped onto the middle of the wheel. If the wheel is balanced, the ball

is equally likely to settle in any of the numbered slots. Imagine spinning a fair wheel once. Define events B: ball lands in a black slot, and E: ball lands in an even numbered slot. (Treat 0and 00as even numbers.)

(a) Make a two-way table that displays the sample space in terms of events B and E.
