Answer:
Answer will be 4
Step-by-step explanation:
Okay, again solve all the exponents.
16^5/4=32
16^1/4=2
Multiply 32x2= 64
For the denominator:
16^1/2= 4
4^2= 16
Your left with 64/16
Divide 64/16 and that will give you 4

Solution :
a). The probability that the student will the 1st question after the 4th attempt.
P (correct in the 4th attempt)
=
= 0.01171875
b). The probability that the student will 3 questions after 10 total attempts.
P( X = 3) for X = B in (n = 10, p = 0.75)
=
= 0.0031
c). The mean and the standard deviation for the number of attempts up to when the students gets all the questions correct is :
There are = 6 success, p = 0.75.
Therefore, this is a case of a negative binomial distribution.
= 8
So,
= 1.6330
