2) Suppose the number of typos in the rough draft of a document is a Poisson random variable with an expected value of 1 typo per page. What is the probability that one page of the document has at least 1 typo?
Solutions
Expert Solution
Probability Mass Function of Poisson Distribution with mean
= 1 is given by:
,
x = 0, 1, ...
P(at least 1 typo) = 1 - P(no typo) = 1 - P(X =0)
So,
Answer is:
0.6321

Poisson. Suppose the principle trombonist misses an average of 2
notes per concert, and the 2nd trombonist misses an average of 5
notes per concert.
