Choose an answer
A.3 balls
B.26 balls
C.4 balls
D.48 balls. There is a small chance he may pick up 47 green balls in a row.
Hint: It's a 15-word phrase with 51 letters, starting with "4".
Answer
48 balls. There is a small chance he may pick up 47 green balls in a row.
Why this is the answer
In the worst possible case, the blind man could draw all 47 green balls in a row before finally getting a red or blue one, so 48 draws guarantee at least two different colors.
