The odds of getting the 5 if you are going to see both the turn and river are 15 to 1. But you cost to the river doubles so you need to figure that into the implied odds. You should be getting about 16.5 to 1 if you were planning to see to this to the river. If you were going to fold if you didn't hit the turn then you need 22 to 1 odds.
