Question
A school cafeteria wants to find out what combinations of food and beverage students are ordering.

Solution
a.) To find the probability that a student ordered a hamburger and a slurpee, we first need to find the total number of orders.
b.) Add up all the numbers in the table: 11+7+23+18+19+5+28+12+14 = 137 total orders.
c.) Next, find the number of students who ordered a hamburger and a slurpee. According to the table, that's 19 students.
d.) The probability is then the number of hamburger and slurpee orders divided by the total number of orders. So, 19/137 = 0.1387 or 13.87%.
So, the probability that a student ordered a hamburger and a slurpee is 13.87%.
