The answers to involving my particular data sheet are as follows:

Average = $38470.00

P (success) = 0.4

Q (failure) = 0.6

what is the probability that exactly 4of them will fall below the average?

=BINOM.DIST(4,10,0.4,FALSE)

0.2508 = 25.08%

what is the probability that fewer than 5of them will fall below the average?

=BINOM.DIST(5,10,0.4,TRUE)

0.8338 = 83.38%

what is the probability that more than 6of them will fall below the average?

=1-BINOM.DIST(6,10,0.4,TRUE)

0.0548 = 5.48%

what is the probability that at least 4of them will fall below the average?

=1-BINOM.DIST(3,10,0.4,TRUE)

0.6177 = 61.77%

IS THIS CORRECT?
