Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins the spinner 180 times. About how many times should Kevin land on red or purple?

Red or purple covers 2 + 2 = 4 of the spinner’s 10 equal sections, so the probability is 4/10. In 180 spins, the expected number is 180 × 4/10 = 72. Therefore, Kevin should land on red or purple about 72 times.
