Will has a spinner with six equal sections numbered one through six. If Will spins the spinner 150 times, how many times can he expect to spin a number less than 5?

Step-by-step answer

There is a 25/150 chance the spinner will land on each number.
25x5 = 125
Therefore he can expect to spin a number less than five 125 times.
Hope this helps
