Answer:
The number of different 7 card hands possibility is 133784560
Step-by-step explanation:
The computation of the number of different 7 card hands possibility is shown below:
Here we use the combination as the orders of choosing it is not significant
So,
The number of the different hands possible would be
=
= 52! ÷ (7! × (52 - 7)!)
= 133784560
Hence, the number of different 7 card hands possibility is 133784560
Answer:
a)0.5611
b)0.1828
c)0.6217
d)0.4389
e)6.25
Step-by-step explanation:
Let's define the following event :
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
