Explanation:

Step1: Identify valid numbers

Numbers from 00 - 74 represent Mondays with quizzes. We have 18 two - digit numbers: 11, 08, 43, 99, 48, 74, 86, 93, 95, 24, 78, 33, 70, 61, 30, 19, 86, 54.

Step2: Count valid numbers

Count the numbers in the range 00 - 74. The valid numbers are 11, 08, 43, 48, 74, 24, 33, 70, 61, 30, 19, 54. There are 12 such numbers.

Step3: Calculate percentage

The percentage is $\frac{12}{18}\times100\%\approx66.7\%$

Answer:

12 out of 18 times, or 66.7%
