Could you help me figure out how to calculate the probability of an event occurring?

The probability of an event occurring can be calculated using the formula P(A)= n(A)/n(S), where n(A) is the number of outcomes of the event, and n(S) is the number of possible outcomes in the sample space. To calculate the probability of an event, you need to identify the number of favorable outcomes and the total number of possible outcomes.
