Answer:
0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Poisson distribution with an average of three errors per page
This means that
What is the probability that a randomly selected page does not need to be retyped?
Probability of at most 3 errors, so:
In which
Then
0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.
