It’s the second one, incompatible
Answer:
LAURA LYONS
Laura Lyons is a typist in the nearby town of Coombe Tracey. An impetuous young woman, she soon found herself exiled from her family after marrying a man possibly because she became pregnant out of wedlock. Her husband soon deserted her, leaving Laura to make a living in whatever way she could. Lyons depends on the generosity of others, including Sir Charles Baskerville. Jack Stapleton preys on Laura’s precarious position in society, and her friendship with Charles Baskerville, to enable his murderous plans against Sir Charles.
BERYL STAPLETON
Beryl Stapleton is Jack Stapleton’s wife, although Jack claims to Dr. Mortimer, Sir Charles Baskerville, Sir Henry Baskerville, Laura Lyons, Dr. Watson, Sherlock Holmes, and others that Beryl is his sister. Although Jack physically abuses Beryl, she remains mostly obedient to him, even allowing Sir Charles to court her at her husband’s request. However, sensing the danger that Sir Charles Baskerville is in, she is quick to try to warn him off of Baskerville Hall, and quick to turn on Jack when Holmes discovers the murderous plot. Beryl is widely known for her beauty, which nearly everyone remarks upon.
Answer:
3. Completing a difficult task
Explanation:
Complete question: In a class of students, the following data table summarizes how many students passed a test and complete the homework due the day of the test. What is the probability that a student chosen randomly from the class passed the test or completed the homework?
Passed the test Failed the test Total
Completed the homework 15 2 17
Did not complete the homework 3 7 10
Total 18 9 27
The probability that a person chosen randomly from the class did not complete the homework is 0.7407
The total number of people in this class = 27
Total number of people that passed = 15 + 3 = 18
We have two events
- Event 1: A random student passed the test
- Event 2: A random student completed the homework
We are to find probability of event 1 or 2
= P(1) +P(2) - P(1 U 2)
P(1) = Probability of those that passed
= 
P(2) = Probability of those that completed homework
= 15+2 = 17
= 
P(1 U 2) = student that passed and did completed homework/total
= 
Probability that a student chosen randomly from the class did not complete the homework
= 
= 0.6667+0.6296-0.5556
= 0.7407
