What are the chances of someone getting into ucla out 100 students?

There's no single answer to the chances of 100 students getting into UCLA. It depends entirely on the academic profile of those 100 students. UCLA's acceptance rate is highly competitive, typically in the single digits (around 10% or lower in recent years).

Therefore:

* If the 100 students are a random sample of all applicants: You'd expect around 10 students to be accepted (10% of 100), but it could be higher or lower depending on the actual applicant pool that year.

* If the 100 students are all exceptionally qualified: A larger percentage might get in, perhaps even a significant majority.

* If the 100 students are all minimally qualified: Very few, if any, might get in.

In short, the probability is highly variable and depends entirely on the qualifications of the students in question. You can't give a meaningful answer without knowing more about those students' GPAs, test scores, extracurricular activities, essays, and other application components.
