The experimental probability of the computer generating a 5 or a 6 is calculated by adding the number of times outcomes 5 and 6 occurred and then dividing by the total number of outcomes:
Number of times outcome 5 occurred: 6
Number of times outcome 6 occurred: 8
Total number of times 5 or 6 occurred: 6 + 8 = 14
Total number of outcomes: 80
Experimental probability = (14 / 80) * 100% = 17.5%
Therefore, the correct answer is:
17.5%
Question
