Answer:
c. The occurrence of the site references in the paper are independent events.
Step-by-step explanation:
For each reference, there are only two possible outcomes. Either it is still good two years later, or it has vanished. So we should try to use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
However, the binomial probability distribution can only be used if the events are independent from each other.
So the correct answer is:
c. The occurrence of the site references in the paper are independent events.
Answer: The last paper has to be 99 over 100 to move the class average by 1 point
Step-by-step explanation:
total points on the 23 exams: 23*75 = 1725
-----
For 24 papers to average 76 points you need 24*76= 1824
---
Score on the final paper would have to be (1824-1725) = 99
