Answer:

And using the probability mass function we got:
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find the following probability:

And using the probability mass function we got:
Answer:
A. 0
Step-by-step explanation:
Nothing can be equal to itself if you subtract 9 from it.
Tax code- Bible = 18528
tax code + Bible = 21472
add the two together to get
2* tax code = 18528 + 21472
tax code = 20000
3^4 + 2 * 5 = 91
The answer is 91.
