Answer:
1/4
Step-by-step explanation:
Answer: Our required probability is 0.167.
Step-by-step explanation:
Since we have given that
n = 15
Probability of success p = 80% = 0.8
Probability of failure q = 20% = 0.2
We need to find the probability that at least fourteen will work.
So, by Binomial distribution, we get that

Hence, our required probability is 0.167.
8 is the value of w and 3 is the value of p
The <em>correct answer</em> is:
C) Line segments have two endpoints and a vertex is a common endpoint where two line segments meet.
Explanation:
A line segment is defined as a portion of a line that has two endpoints.
A vertex is defined as the common endpoint of two or more rays or line segments.
This makes C the correct option.
