उत्तर
Sum of the probabilities of each outcome in an experiment is 1.
Explanation:
If an experiment has n mutually exclusive and exhaustive elementary outcomes \[E_{1}, E_{2}, \ldots, E_{n}\], the sum of their probabilities is always equal to 1.
Mathematically: \[\sum_{i=1}^{n} P(E_{i}) = P(E_{1}) + P(E_{2}) + \cdots + P(E_{n}) = 1\]
