It is supposed that only 50% of the students of a sample will go up to the level master. One chooses by chance 18 students.

Which is the probability so that at least 10 go up to the level master.

I want just to know in this exercise, which is the law of probability that one must apply.

Thank you for your assistance, and I'm so sorry for my bad English.
