The probability that a student studies for a test=P(A)=0.61
The probability that a student gets a good grade on a test=P(B)=0.79
The probability that both occur=
a.We have to find the events are independent

Hence, given events are not independent.
b.We have to find 
c. We have to find

The average is found by adding the numbers and dividing by 2.
Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.
One number is given as 11, so subtract 11 from 34:
34 - 11 = 23
The other number is 23.
Too check: add 11 and 23 and then divide by 2:
11 + 23 = 34
34/2 = 17.
