This is picking without replacing the one that already picked. So first time the probability of getting a boiled egg is 4/12. Now there are only 11 left out of which only 3 are boiled. So second time picking a boiled one will have a probability of 3/11. So the whole probability. will be 4/12 * 3/11

C.

On selecting his first boiled egg, there are 4 boiled eggs out of a total of 12 eggs. Therefore the probability of selecting a boiled egg = 4/12
Now that he keeps the boiled egg, he has 11 eggs left, 3 of which are boiled. In order to select another boiled egg, the probability would be 3/11
So selecting a boiled egg the first and second time would be 4/12 * 3/11
