3 kids can buy a hot lunch salad bar or bring from home. On a slip of paper they each write a number 1,2, Or 3. They add the sum to find the total. If te sum is 3,4, or 5 they buy a hot lunch if it is 6 or 7 they buy a salad bar if the sum is 8 or 9 they bring a lunch from home. If they play they game every day what lunch do you think that they will buy the mOst.?
