Project 2.8

Flower Problem. Three students visited a very patriotic garden of red, white, and blue flowers, but in addition there were some yellow flowers. One student observed that if any four flowers were picked, one of them would be red. Another observed that if any four were picked, at least one of them would be blue. The third shouted that if four were picked, one would be yellow. Does this necessarily mean that if any four were picked, one would be white?
