On average, textbook author makes tWO word-processing errors per page on the first draft of her textbook What is the probability that on the next page she will make (a) 4 or more errors? (6) no errors?
Added by Philip C.
Step 1
Using the Poisson distribution formula, we have: P(X ≥ 4) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)] Substitute the values into the formula: P(X ≥ 4) = 1 - [e^(-2)*2^0/0! + e^(-2)*2^1/1! + e^(-2)*2^2/2! + e^(-2)*2^3/3!] P(X ≥ 4) = 1 - [e^(-2) + 2e^(-2) + Show more…

On average, a textbook author makes two wordprocessing errors per page on the first draft of her textbook. What is the probability that on the next page she will make (a) 4 or more errors? (b) no errors?

Poisson Distribution and the Poisson Process
The number of errors in a textbook follows a Poisson distribution with a mean of 0.01 error per page. What is the probability that there are three or fewer errors in 100 pages?
