37 Suppose four classes have 6, 8, 10, and 40 students, averaging ______. The chance of being in the first class is ______. The expected class size (for the student) is $E(x) = 6\left(\frac{6}{64}\right) + 8\left(\frac{8}{64}\right) + 10\left(\frac{10}{64}\right) + 40\left(\frac{40}{64}\right) = \text{______}$ .

Suppose four classes have 6, 8, 10, and 40 students, averaging ______. The chance of being in the first class is ______. The expected class size (for the student) is
$E (x) = 6 (\frac{6}{64}) + 8 (\frac{8}{64}) + 10 (\frac{10}{64}) + 40 (\frac{40}{64}) =$ ______.
