Certainty FAQs

1. What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
2. How do you calculate basic probability?
Divide the number of favorable outcomes by the total number of possible outcomes. P(A) = n(A) / n(S).
3. What is the range of probability?
Probability always ranges from 0 to 1 (or 0% to 100%). A probability of 0 means the event is impossible, while 1 means it is certain.
4. What are 'Odds' vs 'Probability'?
Probability is the ratio of favorable outcomes to total outcomes. Odds is the ratio of favorable outcomes to unfavorable outcomes (e.g., 1:5 odds means 1 win for every 5 losses).
5. How to calculate probability of independent events?
For two independent events A and B, the probability of both occurring is P(A and B) = P(A) × P(B).
