"Improving a Set to a Boat or Quads"

With pocket Tens, you've luckily made a set on the flop. Unfortunately, the board is all clubs, so you are looking to improve your hand in case anyone out there made a flush. On the flop, you have seven outs: the Ten of Spades would make you quads, and the remaining three Fours and three Aces would make you a full house. Chance of hitting it on the turn is 14.894%.

Note: We aren't calculating the chance on the turn and river combined, or the chance on the river. An additional card on the board would increase your number of outs.
