Assume the number of typo errors on a single page of a book follows Poisson distribution with parameter 1=3. Calculate the probability that on one page there are (i) exactly 2 typos (ii) two or more typo?

(i). 0.03981

(ii).0.0048

Step-by-step explanation:

The probability density function of Poisson distribution is:

Consider X is a number of typos error on a single page of a book and X follows the Poisson distribution with

(i) Exactly two typos:

(ii) Two or more typos:

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
