Question

A chef boiled 4 eggs and put them in a basket with 8 eggs that were not boiled. All of the eggs look the same. Randy selects an egg, keeps it, and then selects another egg. Which expression gives the probability that he selects 2 boiled eggs?

A. 4/12*3/11
B. 4/12*4/12
C.4/12*3/12
D.4/12*4/11

Answer 1

i took the test and its A

Explanation:

All together there are 12 eggs total with 4 that are non boiled and 8 that are boiled. If he takes out 2 eggs, it then goes from 12 total eggs to 11 then take 1 away from 4 to have 3 so its A. 4/12 * 3/11

Answer 2

Expression A gives the correct probability.

On the first draw, there is a 4/12 chance of choosing a boiled egg because there are 4 boiled eggs and a total of 12 eggs to choose from.

On the second draw, there is a 3/11 chance of choosing a boiled egg because there are 3 boiled eggs and a total of 11 eggs to choose from.
