X : ''Calls involving a fax message''
The random variable X can be modeled as a Binomial random variable.
N ~ Bi(n,p)
N ~ Bi(25,0.25)
Where n is the sample and p is the success probability
Let's also define nCr as the combinatorial number :
The probability function for X is :
Where k is the number of success
a)
b)
c)
d)
e) They are asking us about the expected value for random variable X
In a Binomial random variable :
E(X) = μ = n.p
