Question

On her way to work, Mrs. Larsen gets a green light at a certain traffic light only 30% of the time. She wants to find the probability that she will get a green light at this traffic light all five mornings that she travels to work next week. Use the following randomly generated list of 200 five-digit numbers to answer the questions and find the probability.
Select the digits you will use to represent a favorable outcome.
How many favorable outcomes are on this list? What are they?
Given this simulation, what is the probability that Mrs. Larsen will get a green light at this traffic light all five mornings next week?

Answer 1

A random table is used by picking out values one at a time while closing your eyes. The 5 numbers selected are
99470
10152
09747
45400
72767

Since the values needed are percentage, we will only take the first four digits.
99.47%
10.15%
9.74%
45.40%
72.76%

The average of these values is
47.50%
