if the probablity of the guess is 1/3
prob of copying is 1/8
prob of copying which is the right is 1/8
so what is the probablity of geetting the answer right abd he knows that answer is right?

• prob of coping is 1/8
  prob of coping (ri8)=1/8
  prob of guess and ri8 = 1/8 * 1/3 = 1/24(conditional prob)
  prob that he know the ans {1-{(cping(ri8)+ 1/24)}}
  ==> 1-(1/8+1/24)= 5/6 ans
