Rook vs. Bishop and Pawn

 Is this position here a win for White, a win for Black, or a draw?

draw

Sorry, forgot to explain why. 

White can only win if the pawn is promoted. Black kan block this from happening with the king on the black square. White's white bishop cannot remove the black king.

Black on the other hand can only force a mate with the rook such that the white king is positioned on the edge of the board with the black king positioned just opposing the white king two squares away from the white king (sorry if not properly explained). White can avoid this position easily.

Am I wrong?

All the person with the rook has to do is sacrifice their rook for the pawn.

This position is a draw, because of the king's placement, but in rare cases where the rook can pin the bishop and the king or pawn can't defend, or the king is locked in so the rook can mate, then the rook wins, and the bishop & pawn win if the king can be mated or if the rook is capturable or is winnable by tactics, because otherwise the rook can sacrifice itself for the pawn. (KvK+B is a draw, and K+RvK+B is a draw unless in rare cases with the bishop's king's mobility restricted and then the rook wins)
