if the school has 1,000 students, about how many students can the cafeteria expect to buy pizza?

260

Step-by-step explanation: If you add together all of the students surveyed, you will get 200 students. Because there are 1000 students, you need to divide 1000 by 200. If you do that you get 5, so multiply 52, the number of students surveyed who ate pizza, and 5. When you do that, you get 260.

the expected value of the random variable : 0, 1 and 2
