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.

Answer:

i took the test and its A

Step-by-step 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
