**MathGuru**, Wednesday, March 27, 2013 at 7:59pmMean = np = 800 * .24 = ?

Standard deviation = √npq = √(800)(.24)(.76) = ?

Note: q = 1 - p

Use z-scores:

z = (x - mean)/sd

x = 200

Use a z-table to determine the probability. Remember the question is asking "at most 200" when looking at the table.

I'll let you finish the calculations.
