Answer:
The likelihood that he or she has a pet given that a student does not have a sibling is:
Option: D ( 60%)
Step-by-step explanation:
Let A denote the event that a student does not have a sibling.
Let B denote the event that a students has a pet.
Then A∩B denotes the event that the student does not have a sibling but has a pet.
Let P denote the probability of an event.
Then, we are asked to find:
P(B|A)
We know that:

Also from the table we have:
P(A)=0.25
and P(A∩B)=0.15
Hence,

which in percentage is:

Hence, the likelihood is:
60%
67+1 or other combinations like that
