Ethan has a box of assorted tea bags. There are seven green tea bags, six peppermint tea bags, five lemon tea bags, and six plantation mint tea bags in the box. Ethan predicts that when he picks a tea bag from the box without looking, he will draw a peppermint tea bag one-fourth of the time. Which activity would best allow Ethan to test his prediction?
a. Randomly select a tea bag from the box and see if it is a peppermint tea bag.
b. Randomly select and replace a tea bag 80 times. Then, observe how close to 20 times a peppermint tea bag is drawn.
c. Randomly select a tea bag. Then, continue to draw another tea bag until all six peppermint tea bags are drawn.
d. Randomly select and replace a tea bag 90 times. Then, observe how close to 24 times a peppermint tea bag is drawn.
