The correct answer is 4/15.
Answer:
(i). 0.03981
(ii).0.0048
Step-by-step explanation:
The probability density function of Poisson distribution is:
Consider <em>X</em> is a number of typos error on a single page of a book and <em>X</em> follows the Poisson distribution with 
(i) Exactly two typos:
(ii) Two or more typos:
![\begin{aligned}P(X\geq2,\frac{1}{3})&=1-[P(X=0)+P(X=1)+P(X+2)]\\&=1-[0.7165+0.2388+0.03981]\\&=1-0.9952\\&=0.0048\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DP%28X%5Cgeq2%2C%5Cfrac%7B1%7D%7B3%7D%29%26%3D1-%5BP%28X%3D0%29%2BP%28X%3D1%29%2BP%28X%2B2%29%5D%5C%5C%26%3D1-%5B0.7165%2B0.2388%2B0.03981%5D%5C%5C%26%3D1-0.9952%5C%5C%26%3D0.0048%5Cend%7Baligned%7D)
The ratio would be 4:2. In simplest form, it would be 2:1. The meaning is that since there are 4 flutes, the first ratio number would be 4. Same with the 2 drums. How you would simplify it is that you have to minus it down. Since 2 can go into 4, the logical answer would have to be 2:1
