Answer:
The answer is explained below
Step-by-step explanation:
The question is not complete we need point P and point Q.
let us assume P is at (3,1) and Q is at (-2,4)
To find the coordinate of the point that divides a line segment PQ with point P at and point Q at
in the proportion a:b, we use the formula:
line segment PQ is divided in the ratio 5:3 let us assume P is at (3,1) and Q is at (-2,4). Therefore:
Recall that for 
, i.e. a random variable 
following a binomial distribution over 
trials and with probability parameter 
,
So you have
The expected value of is simply 
, while the standard deviation is 
. In this case, they are 
and 
, respectively.
So you have
The expected value of
