Answer: 
Step-by-step explanation:
Let A = he known the answer then A' = he guess the answer.
B = he answered it correctly
As per given , we have
By Bayes theorem , we have
The probability that the student knows the answer given that he answered it correctly is .
First you would convert it to a fraction. 9/100
Once you do that you divide the numerator, which is 9 by the denominator, which is 100.
Then we get our answer, 0.09
