<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 that the first ball is white is (3/8), while the probability that the second one is white is (2/7). Multiplying these shows us that the odds of picking two white balls are 6 to 56 or 10.7%.</s>\ <s>[INST] What is the probability that a ball picked from the bowl is mauve? [/INST] the bowl only contains white and black balls, therefore the probability of picking a mauve ball is 0.</s>
