Please build model in Excel instead simply using equation to solve the problem
Joe drives through three traffic lights, A, B, and C. The probability that any one light is green is 0.3, and the
probability that it is not green is 0.7. Use a simulation to answer questions below. Run 2000 trials. Assume
that the lights operate independently.
Part 1:
What is the probability that Joe will find all traffic lights to be green?
What is the probability that Joe will find at least one traffic light to be green?
Part 2:
Modify the problem to determine how long Joe takes to get to work if the following information is
provided. The probabilities are green (0.30), yellow (0.20), and red (0.50). If it is yellow, then 1 out of 5
times, she makes it through the yellow light without stopping. If all lights are green, it takes her 15
minutes to get to work. For each that is red, it adds two minutes to her trip. If she stops at a yellow light, it
adds 3 minutes to her trip.
On average how long will it take for Anne to get to work?

$8How Our Dissertation Writing Service Works
First, you will need to complete an order form. It's not difficult but, if anything is unclear, you may always chat with us so that we can guide you through it. On the order form, you will need to include some basic information concerning your order: subject, topic, number of pages, etc. We also encourage our clients to upload any relevant information or sources that will help.
Complete the order form
Once we have all the information and instructions that we need, we select the most suitable writer for your assignment. While everything seems to be clear, the writer, who has complete knowledge of the subject, may need clarification from you. It is at that point that you would receive a call or email from us.
Writer’s assignment
As soon as the writer has finished, it will be delivered both to the website and to your email address so that you will not miss it. If your deadline is close at hand, we will place a call to you to make sure that you receive the paper on time.
