The number of times she should expect the pointer to land on either green or yellow based on the probability is 60 times.
From the information, Tamika has a spinner with 5 equal sections – red, blue, green, yellow, and purple and she plans to spin it 150 times.
Therefore, the probability of each color occuring is 1/5.
The number of times she should expect the pointer to land on either green or yellow will be:
= (1/5 + 1/5) × 150
= 2/5 × 150
= 60
