3+4+5=12 potatoes
probability of first one being yellow is 4/12 reduces to 1/3
without replacement
probability of second being yellow is 3/11
<span>probability of both is : 1/3 * 3/11 = 3/33 = 0.09</span>
You have 12 potatoes. Your first draw is 2/12
If you get 1 yellow then you have 1 yellow left and 11 to choose from 1/11
The result is 2/12 * 1/11 = 2/132 = 1/66 of picking out the two yellow potatoes.
