This becomes 10:22, then 5:11.
Answer:
0.599 is the probability that a randomly selected page does not need to be retyped.
Step-by-step explanation:
We are given the following in the question:
The number of typing errors made by a typist has a Poisson distribution.

The probability is given by:
We have to find the probability that a randomly selected page does not need to be retyped
P(less than or equal to 7 mistakes in a page)

Thus, 0.599 is the probability that a randomly selected page does not need to be retyped.
Translate the English to Math language:
Let x be that number
2x -3 = x-6 solve for x ; x=-3
Part c=t, part a=h,t
I'm sorry.but I'm not sure of part b
