(a) P(X ≥ 3.5) if X ∼ N(2,4),
(b) P(X ≥ −4) if X ∼ N(−5,1).

You can put this solution on YOUR website! If X ∼ N(µ ,σ^2)
Using Handheld TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
(a) P(X ≥ 3.5), if X ∼ N(2,4) = normcdf(3.5,9999,2,2) = .2266
(b) P(X ≥ −4), if X ∼ N(−5,1) = normcdf(-4,9999,1,-5) = .1587
