How can I solve probability

Identify what you are trying to find the probability of.

This is the size of your sample space.

This is the number of outcomes that satisfy the event you are interested in.

The probability of an event is the ratio of favorable outcomes to the total number of possible outcomes.

The formula for probability is:

For example, if you want to find the probability of rolling a 4 on a standard six-sided die:

• The event is rolling a 4.
• The total number of possible outcomes is 6 (numbers 1 through 6).
• The number of favorable outcomes is 1 (only the number 4).
• The probability is $P(\text{rolling a 4}) = \frac{1}{6}$.
