What is the difference between conditional probability and independent probability?
For independent events, one event does not affect the probability of another: P(A and B) equals P(A) times P(B). For conditional probability, event A affects the probability of B: P(B|A) equals P(A and B) divided by P(A). If P(B|A) equals P(B), then A and B are independent.
❓ Quick answer
What does a probability of 0.5 mean?
A probability of 0.5 or 50 percent means the event is equally likely to occur or not occur. It represents maximum uncertainty between two outcomes. Flipping a fair coin has probability 0.5 of getting heads.
❓ Quick answer
Why does experimental probability differ from theoretical probability?
Experimental probability is based on actual results which include randomness and variation. Theoretical probability is the true long-term average. With few trials, they differ significantly. As trials increase, experimental probability converges to theoretical probability due to the Law of Large Numbers.
