Question

8 If Brian spins the spinner 112 times, how many times should he expect the spinner to land on thenumber 7? Show your work.8172.6354

Answer 1

First, we find the probability of 7.

`P=(1)/(8)`

Because there is one number 7 out of 8.

Then, we multiply this probability by 112

`E=(1)/(8)\cdot112=14`

Hence, it's expected to land 14 times.
