I disagree.

In a game between humans white has chances because he has chances to capture all
the black pawns and win the KRB vs KR endgame.

In a game between computers white has also chances if the defender does not use
the KRB vs KR tablebases.

It is a draw but I prefer white because white captures one pawn and is not going
to lose with Rook and bishop against Rook and 2 pawns beacause the pawns are at
a7 and b6 and the king is in the middle of the board so it is easy for white to
prevent the pawns to get forward.

Black practically may lose by the following steps:
1)losing the pawns
2)not finding the right moves in KR vs KRB endgame.
