There are 250 tables total in a cafeteria. There are 150 tables with red tablecloths and 100 tables with white tablecloths. As p
eople walk into the cafeteria they are randomly assigned to a table. What is the probability of the first person through the door of being sat at a table with a red tablecloth? SIMPLIFY
If there are 250 tables you can multiply it by 4 to work with 1000. This means you have to multiply the other table cloth numbers. 150 x 4 = 600. 100 x 4 = 400. Once you simplify you can get 40 white and 60 red out of 100. 60/100 = 60%.
