Every day, navya's teacher randomly picks a number from 1 to 80 to be the number of the day. 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 60. the number of days in which a number chosen is greater than 60 is

The number of days the number will be greater than 60 is 45.  

Step-by-step explanation:

Since there are 80 total numbers and a number of the day can be repeated, then there is the same chance each day of picking one of the numbers.  There are 20 numbers greater than 60 between 1 and 80.  So, the chances of picking a number greater than 60 each day is 20/80, or 1/4 (25%).  This probability is the same each day and we would take the total number of school days (180) multiplied by this probability to get our predicted number of days the number would be greater than 60 during the school year.  180 x .25 = 45.
