Calling wins $300 if villain doesn't make a flush, and loses $2800 if he does. Thus for hero to break even by calling, villain has to make a flush less than 1 in 10 times. If villain has the FD he has a 1 in 5 chance of hitting, so he has a 1 in 10 chance of making the flush if he has the FD half the time.
