Boxes Of Balls Riddle
The first box has two white balls. The second box has two black balls. The third box has a white and a black ball.
Boxes are labeled but all labels are wrong!
You are allowed to open one box, pick one ball at random, see its color and put it back into the box, without seeing the color of the other ball.

Hint:
Just One!
Because we know all labels are wrong.
So the BW box must be either BB or WW. Selecting one ball from BW will let you know which.
And the other two boxes can then be worked out logically. Did you answer this riddle correctly?
YES NO

How Many Balls Riddle
In the drawer beside your bed, you have three orange, two pink and five purple balls. There is no electricity and the room is completely dark. How many balls you must take out to make sure you have one ball of each color at least?
Hint:
9
2 < 3 < 5
To find out the required number of balls, take one in place of the least number (i.e. take one pink ball) and then add all the greater numbers (i.e. three orange and five purple balls) to it.
Required number of balls = 1 + 3 + 5 = 9. Did you answer this riddle correctly?
YES NO

Redmonds Runs Riddle
During a baseball game in Redmond, John was Redmonds lead-off batter. There were no substitutions or changes in the Redmond batting order at all during the nine-inning game. John came to bat in every inning. What is the least number of runs Redmond could have scored?
Hint:
Zero. In the first inning John and the next two batters walk and the next three strike out. In the second inning, the first three walk again, which brings John back to bat. But each runner is caught off base by the pitcher, so John is back at the plate at the start of the third inning. This pattern is now repeated until the game ends with no joy in Redmund, even though the mighty John never once strikes out. Did you answer this riddle correctly?
YES NO
YES NO
