Simply create a scatter plot then write in a line of best fit.
I'm not 100% sure
Answer: 0.6767
Step-by-step explanation:
Given : Mean =
errors per page
Let X be the number of errors in a particular page.
The formula to calculate the Poisson distribution is given by :_
![P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5Cdfrac%7Be%5E%7B-%5Clambda%7D%5Clambda%5Ex%7D%7Bx%21%7D)
Now, the probability that a randomly selected page does not need to be retyped is given by :-
![P(X\leq2)=P(0)+P(1)+P(2)\\\\=(\dfrac{e^{-2}2^0}{0!}+\dfrac{e^{-2}2^1}{1!}+\dfrac{e^{-2}2^2}{2!})\\\\=0.135335283237+0.270670566473+0.270670566473\\\\=0.676676416183\approx0.6767](https://tex.z-dn.net/?f=P%28X%5Cleq2%29%3DP%280%29%2BP%281%29%2BP%282%29%5C%5C%5C%5C%3D%28%5Cdfrac%7Be%5E%7B-2%7D2%5E0%7D%7B0%21%7D%2B%5Cdfrac%7Be%5E%7B-2%7D2%5E1%7D%7B1%21%7D%2B%5Cdfrac%7Be%5E%7B-2%7D2%5E2%7D%7B2%21%7D%29%5C%5C%5C%5C%3D0.135335283237%2B0.270670566473%2B0.270670566473%5C%5C%5C%5C%3D0.676676416183%5Capprox0.6767)
Hence, the required probability :- 0.6767
