Question 924047: Question - 1: Certain types of photographic film are produced and sold in rolls of 100 meters. If the expected number of defects on film rolls is 15 per 100 meters.What is the probability that no more than two defects occur in any 10 meters length? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! p = 15/100 = .15, n = 10
Using TI or similarly a Casio fx-115 ES plus
P(x ≤ 2) = binomcdf(10, .15, 2) = .8202 0r 82.02%
