To find the theoretical probability of 3 students from your school being selected as contestants out of 9 possible contestant spots, we need to calculate the number of ways to choose 3 students from your school out of the total number of ways to choose 9 contestants out of the total audience.

The total number of ways to choose 9 contestants out of 130 audience members is given by the combination formula C(130, 9) which is calculated as follows:

C(130, 9) = 130! / (9! * (130-9)!) = 2.802075092 × 10^12

Next, we calculate the number of ways to choose 3 students from your school out of the total 9 contestants spots. This is given by the combination formula C(9, 3) which is calculated as follows:

C(9, 3) = 9! / (3! * (9-3)!) = 84

Therefore, the probability of 3 students from your school being selected as contestants is:

P(3 students selected) = C(9, 3) / C(130, 9) = 84 / 2.802075092 × 10^12 ≈ 0.000000000030

Rounded to three decimal places, the theoretical probability is approximately 0.000.

I apologize for the error in my previous response. Let's correct it.

To find the theoretical probability of 3 students from your school being selected as contestants out of 9 possible contestant spots, we need to calculate the number of ways to choose 3 students from your school out of the total number of ways to choose 9 contestants out of the total audience.

The total number of ways to choose 9 contestants out of 130 audience members is given by the combination formula C(130, 9) which is calculated as follows:

C(130, 9) = 130! / (9! * (130-9)!) = 56,087,800

Next, we calculate the number of ways to choose 3 students from your school out of the total 9 contestants spots. This is given by the combination formula C(9, 3) which is calculated as follows:

C(9, 3) = 9! / (3! * (9-3)!) = 84

Therefore, the probability of 3 students from your school being selected as contestants is:

P(3 students selected) = C(9, 3) / C(130, 9) = 84 / 56,087,800 ≈ 0.000001498

Rounded to three decimal places, the theoretical probability is approximately 0.000.
