Answer:
The probability that the sample will contain exactly 0 nonconforming units is P=0.25.
The probability that the sample will contain exactly 1 nonconforming units is P=0.51.
.
Step-by-step explanation:
We have a sample of size n=4, taken out of a lot of N=12 units, where K=3 are non-conforming units.
We can write the probability mass function as:
where k is the number of non-conforming units on the sample of n=4.
We can calculate the probability of getting no non-conforming units (k=0) as:
We can calculate the probability of getting one non-conforming units (k=1) as:
Answer:
Exact form:
Decimal form:
The solution for x is: The solution for x is of 10.455º
Step-by-step explanation:
We are given the following equation:
Placing into the desired format, the exact format is:
In the decimal part, we divide 8 by 9. So
Solving for x:
We apply the inverse sine. So
The solution for x is of 10.455º
