Eshootzi_scrs Apr 25, 2007	OK it was simple to add the fruits and come up with 6 blueberries. So the math works the same 10/36. The real problem is the human factor. There is NO WAY a person is reaching into a bowl, even if they arent looking, and mistaking a banana for a blueberrie or an apple. There for rule out the bananas -7. Again no one mistakes an orange for either an apple or a blueberrie, -11. Cherries are larger than bluberries and smaller than apples, -8. Thats 26 out of 36 that she wont pick leaving only 10 that she likes and will pick. The probability therefore is 100%. Put simply if you put three people into a room what are the odds you will find yourself.

Bgjhn Jul 29, 2008	Thought something wrong, bananas threw the #'s off. food for thought though.
javaguru Dec 23, 2008	I came up with the same answer and reasoning as Eshootzi: 100%.
