What are three ways to express the probability of an event that occur 500 times out of 2000 total trails?

The probability of an event occurring can be expressed in several ways:

1. As a fraction, it would be ( \frac{500}{2000} ), which simplifies to ( \frac{1}{4} ).
2. As a decimal, it would be 0.25.
3. As a percentage, it would be 25%.
