About 13.3 in 100 sets of the first seven tiles from a full French Scrabble bag contain at least one blank joker.

Calculation

p = 1 − C(100, 7) / C(102, 7) ≈ 0.1331780

Assumptions

Seven tiles are drawn without replacement from the complete French bag. It contains 100 printed letter tiles and two blank jokers, and each tile is equally likely to be drawn. Jokers are the only blank tiles.
