The basic probability formula $P(\text{event}) = \frac{\text{number of favorable outcomes}}{\text{total number of possible outcomes}}$ can only be applied when which condition is met?

There are at least 10 possible outcomes.

All outcomes are equally likely.

The probability is greater than $\frac{1}{2}$.

The number of favorable outcomes is 1.

A box contains 10 balls: 5 are red, 3 are blue, and 2 are green. Which statement is true about drawing one ball at random?

The outcomes 'drawing red' and 'drawing blue' are equally likely.

Drawing a green ball is the most likely outcome.

Each of the 10 individual balls has an equal chance of being drawn.

The outcomes are not equally likely, so probability cannot be calculated.
