Question

The number of typographical errors per page typed by a certain typist follows a Poisson distribution with a mean of t.

Then find the probability p that the total number of errors in 17 randomly selected pages is 8.

(needs actual probability)

Answer 1

The probability that the total number of errors in 17 randomly selected pages is 8 can be calculated using the Poisson distribution.

Step-by-step explanation:

To find the probability that the total number of errors in 17 randomly selected pages is 8, we need to use the Poisson distribution. In a Poisson distribution, the mean is given as 't'. Since the mean number of typographical errors per page is 't', the mean number of errors over 17 pages would be 17t.

We can use the formula for the Poisson distribution to calculate the probability: P(x = 8) = (e^(-17t) * (17t)^8) / 8!.

However, we don't have the actual value of 't', so we cannot find the exact probability without that information.
