A class quiz has 5 True/False questions. The correct answers are T, T, F, F, and T, in that order. John answered the questions randomly and is now wondering if he will pass the quiz. He needs to have at least 3 correct answers. John 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? Trial 1 is fail with numbers 22, 33, 18, 45, 80. Trial 2 is pass with numbers 11, 3, 72, 98, 67. Trial 3 is fail with numbers 28, 36, 43, 85, 71. Trial 4 is pass with numbers 27, 56, 41, 90, 55. Trial 5 is fail with numbers 12, 34, 20, 59, 31. Trial 6 is pass with numbers 11, 7, 50, 28, 32. Trial 7 is fail with numbers 17, 44, 76, 39, 20. Trial 8 is pass with numbers 2, 93, 53, 38, 29. Experimental probability =
