i ment to put bananas not blue berries
lol good one
you people r confusing me This makes perfect sense.
good one.
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.
