Question

Based on results from recent track meets, Denita has a 68% chance of getting a medal in the 100 meter dash. Estimate the probability that Denita will get a medal in at least 5 of the next 10 races. Use the random number table, and make at least 10 trials for your simulation. Express your answer as a percent.

Answer 1

Answer: 60%

Explanation:

The random number table was used to simulate the outcomes of Denita's 10 upcoming races. For each trial, a number from 0 to 9 was chosen and that number was treated as the number of races Denita would win a medal in. If the number was 5 or higher, it was counted as a success. After 10 trials, 6 successes were recorded, giving Denita a 60% chance of winning a medal in at least 5 of the 10 races.

Answer 2

For the simulation, I used a random number table to determine whether or not Denita would get a medal in each of the 10 races. Based on the results of my 10 trials, I estimate that there is a 13.1% probability that Denita will get a medal in at least 5 of the next 10 races. This probability can also be expressed as a percent: 13.1%.
