Question

PLSS HELP!!!!!!!!!!

A computer generates 80 integers from 1 to 8 at random. The results are recorded in this table.

Outcome 1 2 3 4 5 6 7 8
Number of times outcome occurred 14 16 10 12 4 7 6 11

What is the experimental probability of the computer generating a 2 or a 5?

Answer 1

25%

Explanation:

To find the experimental probability of the computer generating a 2 or a 5, we need to calculate the total number of times the outcomes 2 and 5 occurred and divide it by the total number of trials (which is 80 in this case).

Looking at the table, the outcome 2 occurred 16 times and the outcome 5 occurred 4 times.

Total number of times 2 or 5 occurred = 16 + 4 = 20

Experimental probability = (Number of times 2 or 5 occurred) / (Total number of trials) = 20 / 80 = 0.25

To express this as a percentage, we multiply the decimal value by 100:

Experimental probability = 0.25 * 100 = 25%

Therefore, the correct answer is 25%.
