For only Brian to succeed, Matt and Andrew must fail.
Matt (Failure) = 2/5
Brian (Success) = 4/7
Andrew (Failure) = 7/8
--> (2/5) * (4/7) * (7/8) = 1/5
The answer is B.
Matt (Failure) = 2/5
Brian (Success) = 4/7
Andrew (Failure) = 7/8
--> (2/5) * (4/7) * (7/8) = 1/5
The answer is B.

I had one doubt. There can be a case where Brian succeeds first, Or Brian succeeds second, or Brian succeeds third it can be MBA, MAB, AMB, BAM, and so on...
The equation will be this:
P(Matt failed) x P(Brian succeeded) x P(Andrew failed) x 3!
why is the equation wrong?
