Achef boiled four eggs and put them in a basket with eight eggs that were not boiled all of the eggs look the same randy selects an egg and keeps it then selects another egg which expression gives the probability that he selects two boiled eggs

The correct answer is the 3rd choice:

4/12 x 3/11

The explanation is that to start there are 12 total eggs of which 4 of them are boiled, so there is a 4/12 chance that the chef will get a hard boiled egg.

After removing one of the hard boiled eggs, there will be 3 hard boiled eggs remaining and one less total eggs (11).

To find the probability of getting a hard boiled egg both times, you multiply both probabilities together.
