Question

Suppose Kalvin spins the pointer 64 times. Based on your experiment, how many times can you expect the pointer to land on 9:00, on 10:00 and on 11:00?

Answer 1

16 times out of 64

Explanation:

So, I could be wrong, but basically:

9, 10, and 11 are only 3 of the 12 possible outcomes that could happen.

3 out of 12 is 1/4.

What this means is that for every 4 times he spins the pointer, he can expect to get 9, 10, or 10 once.

Or 25% of the time

1/4 of 64 is 16.
