Answer 2

For the 1st question
The even of getting an A is dependent
(because it depends on whether or not the student studied for the test) thus

The possibility of having a random student who had an A and did not study.
By the table you need to know the total number of the students who got an A
That would be 7
And now you have to find the total number of those who earned A and didn't study which is only 1
Therefore the possibility is 1/7

Answer 3

so the answer is dependent 1/7

Answer 4
