Answer

Answer:

B. 80

Explanation:

Step1: Calculate probability of landing on purple or orange

The spinner has 5 equal - sections. The probability of landing on purple or orange is $\frac{2}{5}$ since there are 2 favorable outcomes (purple and orange) out of 5 total outcomes.

Step2: Calculate expected number of times

We spin the spinner 200 times. The expected number of times is the probability times the number of trials. So, $E = \frac{2}{5}\times200= 80$.
