Question 925347: suppose that on the average 2 person in 1000 make a numerical error in preparing
his income tax return,if 10,000 form are selected at random and examined.find the probability that 6 of the form contain error . ? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! p(error) = 2/1000 = .002, n = 10,000
Using a TI calculator 0r similarly a Casio fx-115 ES plus
P(x = 6) = binompdf(10000, .002, 6) = .0002 0r .02%
