Question 182175: This question was written by the professor who doesn't use books in his class.
In a package of candies, 8 candies are green, 2 are red and 6 are white. If the first candy chosen in NOT white, what is the probability that the next one will be white (assume 1st candy was NOT put back in)?

There are originally 8+2 = 10 candies that are not white
There are 6 white ones
If you take one non-white one out, there are 9 non-white ones left
There are still 6 white ones in there.
So the probability of drawing a white one on the second pull is 6 chances out of the total candies left. There are 15 candies still left (9 nonwhite and 6 white).
So the probability is 6:15 which simplifies to 2:5 or 40% chance
