Simulating Coin Flips (Example 21)
a. Use the line of random numbers below to simulate flipping a coin 20 times. Use the digits 0, 1, 2, 3, 4 to represent heads and the digits 5, 6, 7, 8, 9 to represent tails.
11164 36318 75061 37674
b. Based on these 20 trials, what is the simulated probability of getting heads? How does this
compare with the theoretical probability of getting heads?
c. Suppose you repeated your simulation 1000 times and used the simulation to find the
simulated probability of getting heads. How would the simulated probability compare with the
theoretical probability of getting heads?

- Flexible Work Hours In a recent survey, people were asked whether they would prefer to work flexible hours----even when it meant slower career advancement----so they could spend more time with their families. The figure shows the results of the survey. What is the probability that three people chosen at random would prefer flexible work hours?arrow_forwardIn Example 8, what is the probability that an employee chosen at random has 30 or more years of service?arrow_forwardWhat is an experiment? Give two examples.arrow_forward
- What is the difference between events and outcomes? Give an example of both using the sample space of tossing a coin 50 times.arrow_forwardIn Example 10, researchers selected five people at random from the population. What is the probability that all five people expected much of the workforce to be automated within 50 years?arrow_forward
