Yea it's possible they win out. If you give them a 60% chance to win in each of their last 4 games (which may be optimistic in some cases, pessimistic in others), then the chance of winning all four is roughly 13% (.6 ^ 4). The chance of winning 3 of 4 would be 35% ((.6 ^ 3 * .4 ) * 4). That leaves a 52% chance the Bills win two or less, which would most likely not be good enough to make playoffs. Obviously depending on what odds you give the Bills in each individual game, the combined odds would differ.
