Once a legendary bow drops, the game "rolls" which one exactly it is, based on the roll weights/rarity.
There are mostly 3 types of rarity, some exceptions:
common = 100 (most stuff)
uncommon = 50 (K'mar Tenclip, Thunderfury for e.g.)
rare = 10 (Like Wand of Woh, Kridershot, Calamity, Rimeheart)
The actual chance depends on the items' group. To sum it up:
Quote
pre 2.1: 6 bows.
5x 100 (Raven/Uskang/Etrayu/Cluckeye/Windforce) = 19.61% each
1x 10 (Kridershot) = 1.96%
2.1: 6 bows
3x 100 (Raven/Cluckeye/Windforce) = 24.39% each
2x 50 (Uskang/Etrayu) = 12.2% each
1x 10 (Kridershot) = 2.44%
2.1 season: 7 bows
4x 100 (Raven/Cluckeye/Windforce/Leonisomething... bola bow) = 19.61% each
2x 50 (Uskang/Etrayu) = 9.8% each
1x 10 (Kridershot) = 1.96%
-> Seasons has a slightly lower chance to get good bows.
