Problem Statement

How do you calculate probability?

Step-by-Step Explanation

Probability compares favorable outcomes to all possible outcomes when outcomes are equally likely.

  1. Identify what the question is asking. In Probability, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Key Formula

P(A)=favorable outcomestotal outcomesP(A)=\frac{\text{favorable outcomes}}{\text{total outcomes}}

Final Answer

Probability compares favorable outcomes to all possible outcomes when outcomes are equally likely. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
