A Gaussian random variable has a PDF of the form

Write each of the following probabilities in terms of Q- functions (with positive arguments) and also give numerical evaluations:
(a) (X > 0),
(b) (X > 2),
(c) (X > €“3),
(d) (X > €“ 4),
(e) (X + 1| > 3),
(f) (X + 1| (g) (X + 2| > 1),
(h) (X €“ 1| > 2).

(x) = exp(-2(x+ 1)2 ) .
