<s>[INST] Alice has a bowl with 8 balls. Three of the balls are white and the rest are black. Bob picks two balls from the bowl at random. What is the probability that both balls are white? [/INST] The probability of Bob picking two white balls from the bowl is:

(number of ways to choose 2 white balls from 3) / (number of ways to choose 2 balls from 8) = (3C2) / (8C2) = (3!) / ((8!) / (2! * 6!)) = 3 / 28 = 1/9.

So the probability that both balls are white is 1/9.</s>\ <s>[INST] 3C2 = 3! / (2! * (3-2)!) = 6 / 2 = 3 not (3!) otherwise the calculation seems correct, thanks [/INST]
