A sports journalist ran a simulation to determine which Olympic athlete would win the 100-meter sprint. She ran the simulation 200 times and recorded the results in the following table.

Question

Athlete: A B C D
Number of Wins: 59 58 45 38

Based on the data from the simulation, what is the probability of athlete A or D winning the event?

A) 0.380
B) 0.415
C) 0.485
D) 0.585

Answer 1

To find the probability of either athlete A or D winning the event based on the simulation results, we first need to calculate the total number of wins by athletes A and D.

From the table provided:

• Athlete A won 59 times.
• Athlete D won 38 times.

Now, we can calculate the total number of wins for A and D: $$\text{Total Wins (A and D)}=\text{Wins by A}+\text{Wins by D}=59+38=97$$

Next, we find the total number of simulations: $$\text{Total Simulations}=200$$

Now we can calculate the probability of either athlete A or D winning: $$\text{Probability (A or D)}=\frac{\text{Total Wins (A and D)}}{\text{Total Simulations}}=\frac{97}{200}$$

Calculating this gives: $$\frac{97}{200}=0.485$$

Thus, the probability of athlete A or D winning the event is 0.485.

The correct answer is C) 0.485.
