Find the area under the standard normal curve for the following:
(A) P(z > 0.90)
(B) P(-1.17 < z < 0)
(C) P(-0.58 < z < 1.57)
table is a "cumulative standard normal table (so it gives area to the left of the z-score) and has positive and negative z-scores shown".

I suggest you purchase a TI-84+ calculator.
-------------------------
(A) P(z > 0.90) = normalcdf(0.90,100) = 0.1841
-----
normalcdf sums up the area under the normal curve
over the z-interval [0.9,100]
--------------
(B) P(-1.17 < z < 0) = normalcdf(-1.17,0) = 0.3790
normalcdf sums up the area under the normal curve
over the z-interval (-1.17,0)
------------------
(C) P(-0.58 < z < 1.57) = normalcdf(-0.58,1.57) = 0.4649
