To find the area under a normal distrubution curve use a z-score table, in the table you can identify the area under a z-score.
If you use the table for the z-score -1.82 you get the non-shaded area, but as the total area under the curve is 1 you subtract the value corresponding -1.82 from 1 to get the area of the shaded area
Area under -1.82:
Area of the shaded region:
[tex]1-0.0344=0.9656[/tex]
Then, the area of the shaded region is 0.9656
