Probability that part is good and you reject it:

Probability that given a part is bad, you accept it (false accept):

F_{(X,Y)} is the cumulative distribution function (CDF) of the bivariate normal random vector (X,Y)^{T} with:

mean, μ = (θ,θ)^{T}

F_{(X)} and F_{(Y)} are the corresponding marginal CDFs.
