Use the algebra tiles to model x – 3. Then complete the statements. The variable is represented by Subtracting three is represented by. The tiles represent an unknown number.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
