The spinner below was spun 50 times. The results of each spin are shown in the table below. If you were to spin the spinner 300 times, how many times would you expect the spinner to land on yellow based on the experiment?

A die was rolled 40 times. The results of each roll is given in the table below. What is the experimental probability of roling a 2 or 3?

A die was rolled 40 times. The results of each roll is given in the table below. Based on the experimenta; probability, if a die is rolled 120 times, how many times can someone expect to roll an even number?
