    Easy problem, but if you answer as plain text, you need to select "Plain Text" in the dropdown list. I got it wrong twice with the right answer before realizing this.

    By variance sum law: (SD of x-y)^2=(SD of x)^2 +(SD of y)^2

    X and Y are random variables, not deviates. Deviate is the actual outcome of the variable.
