A person's white blood cell (WBC) count W (measured in thousands o0f cells per microliter of blood) and body temperature T (in degrees Celsius) can be modeled as bivariate Gaussian random variables such that W is Gaussian (7,2) and T is Gaussian (37.1). to determine whether a person is sick, first the person's temperature is measured. If T > 38, then the person's WBC count is measured. If W > 10, then the person is declared ill (event I).

Suppose W and T are uncorrelated. What is P[I]?
