Every day Abby's teacher picks a number of the day from 1 to 20. The number of the day can be repeated. There are 180 days in the school year. Predict how many days the number of the day will be greater than 15.

Well, greater than fifteen would mean there are 4 numbers, or 4/20 chance, knowing this, we can predict by dividing 180 by 4, which would equal 45 days in which the number of the day would be greater than 15
