If a trial has k equally likely outcomes, of which one and only one will happen, the probability of any individual outcome will be:

Correct option is A

Definition of Probability:
· Probability is defined as:

Equally Likely Outcomes:

Information Booster: 1. Equally Likely Outcomes:
· Outcomes have the same likelihood of occurring, e.g., rolling a fair die (1/6 probability for each side).
2. Applications of Probability:
· Used in games, statistics, and decision-making under uncertainty.
3. Compound Events:
· For two independent events, probabilities multiply: P(A∩B)=P(A)⋅P(B).
