The following is a probability distribution function for X, with range 0, 1, 2, 3: P(X = 0) = 0.1; P(X = 1) = 0.3; P(X = 2) = 0.4; P(X = 3) = 0.2. Compute E(X). Round your answer to one decimal place.

okay wait before i answer, is this for your points on a graph?

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
