Question 1151401: If X is normal with mean 0 and variance 4 then find the probability of the
event when X - 4/X is positive i.e X - 4/X is greater than zero?

This would occur when x is greater than 4.
that probability with variance 4 and sd 2 would be greater than 2 sd s from the mean (positive) or 0.0228.
