Red, Blue, Yellow, & BleachDiscrete Mathematics Level 3
Three balls of the same size but different colors (red, blue, yellow) are placed randomly on the tray with 6 holes. Then the springer above will randomly pour down the bleach into 3 out of the 6 holes.
Once bleached, any color will turn white, and the chemical may hit 1 ball, 2 balls, 3 balls, or none at all.
How many sets of color balls are there in this scenario?
