A and B are two weak students of statistics and their chance
of solving a problem in statistics correctly are 1/6 and 1/8 respectively.

and they obtain the same answer find the probability that the
answer is correcr

Answer:
probability of solving p(E1)= 1/6×1/8=48
for unsolve answer= 5/6×7/8=35/48
Let E is the same answer attempt so p(E/E1)=1
PE/E2) =1/525
p(E1/E) =
P(E1)×PE/E1)/P(E1)×P(E/E1)+P(E2)×P(E/E2)
Now Solve your self!!
answer is 15/16
