A manuscript is sent to a typing firm consisting of typists A, B, and C. If it is typed by A, then the number of errors made is
a Poisson random variable with mean 2.6: if typed by B, then the number of errors is a Poisson random variable with mean 3: and if typed by C, then it is a Poisson random variable with mean 3.4. Let X denote the number of errors in the typed manuscript. Assume that each typist is equally likely to do the work. Find E[X] and Var[X].

We are given a figure where M, N , O and P points are given.
We need to explain if points O, N, and P collinear or not.
Note: All co-linear points are in a straight line.
From the figure, we can see that <em>O and N points are in a straight line but point P is aside.</em>
So, the points O, N, and P are not collinear.
Therefore, correct option is "<u>No, the three points are not collinear</u>".
