Question 1132286: The expected number of typographical errors on a page of a certain magazine is n=0.60. What is the probability that the next page you read contains :
A) exactly one typographical error ?
B) at least one typographical error ? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Poisson distribution with infinite theoretically possible, count data, proportional to number of chances.
parameter is 0.6
probability of exactly 1 is e^(-0.6)*0.6^1/1!=0.3293
At least 1 is 1- probability of 0, which is 0.5488, so at least 1 has a probability of 0.4512
