Step-by-step explanation:

Given

n = 1060

See attachment for spinner

Required

Determine the number of times an outcome of 1, 3 or 8 is expected

First, calculate the theoretical probability of 1, 3, or 8

This is calculated as:

Pr = P(1) + P(3) + P(8)

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

$Pr = \frac{1}{8}+\frac{1}{8}+\frac{1}{8}$

Take LCM and add

$Pr = \frac{1+1+1}{8}$

$Pr = \frac{3}{8}$

So, the expected number of times (E) is:

E = Pr * n

$E = \frac{3}{8} * 1060$

$E = \frac{3* 1060}{8}$

$E = \frac{3180}{8}$

E = 397.5

Approximate

E = 398

This means about 400 times
