Question

A spinner has 14 equal sectors with different letters for each sector, as shown below:

A spinner with 14 equal sectors is shown. The sectors are labeled B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.

Victoria spins the spinner 18 times, and it stops at the letter B 10 times. If she spins the spinner a 19th time, what is the theoretical probability that this time it will stop at the letter B?

1 over 20
1 over 18
1 over 14
1 over 10

Answer 1

the correct answer would be 1/14

Answer 2

1 over 14

Explanation:

The sectors labeled are B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.

Total number of sectors = 14.

When Victoria spins the spinner 18 times, and it stops at the letter B 10 times.

When Victoria spins the spinner the theoretical probability that this time it will stop at the letter B = Favourable outcomes ÷total numner of outcomes.

Favourable outcomes =1 and Total number of outcomes = 14.

Hence Theoritical Probability = 1 over 14.
