Wow i feel stupid 3/7*7/7 i think so 21/49 seems more reasonable.
anonymous
  • anonymous
does that seem right?
anonymous
  • anonymous
It makes sense the first time I did I was intending both cans to be cola.
anonymous
  • anonymous
It seems more reasonable, but is still wrong.

Draw a probability tree!

Well than Sir Newton provide your expertise.

Well, your method give the answer 3/7, which is clearly wrong; that's as if only one was picked, and completely ignores what happens if you pick another one first THEN cola; try again, or draw a tree!

3/7*4/7=12/49?
anonymous
  • anonymous
The probability of picking one in two attempts isn't less than picking one in one attempt. Try again.

I dont get it order doesnt matter
anonymous

You either pick one first (3/7) or you pick one of the others first (4/7). If you pick it first (3/7) you can ignore that because whatever you pick next will make it true. For the others (4/7), you now have a 3/6 chance of picking cola. It's (3/7) * 1 + (4/7) * (3/6)
