A number cube was rolled 20 times to represent 20 purchases. What is the experimental probability of receiving a 20% coupon? Write the probability as a decimal.

A class quiz has 5 True/False questions. The correct answers are T, T, F, F, and T, in that order. Brandon answered the questions randomly and is now wondering if he will pass the quiz. He needs to have at least 3 correct answers. Brandon used a calculator to generate random numbers from 1 to 100. He let odd numbers stand for True and even numbers stand for False. He recorded the results in the table. What is the experimental probability that John passed the quiz? Use the chart to answer the question.
