Please help? will vote best answerr :)?

Both are B. Using the calculator found at a href="http://stattrek.com/Tables/normal.aspx" rel="nofollow"http://stattrek.com/Tables/normal.aspx/a you can see that the P(X < 782) is 0.54727. However, since you want greater than you simply do 1 - P and you get .45273 as the answer [or .4527 with rounding as in your case].
