What to Focus On
- Probability is a numerical measure of chance.
- Random experiment: result is uncertain, but possible outcomes are known.
- Experimental probability uses actual trials.
- Equally likely outcomes have equal chance of occurrence.
- Sample space is the set of all possible outcomes.
- For one coin toss, the sample space is {H, T}.
- Experimental probability is an estimate from actual data.
- More trials usually give a more stable probability.
- For a fair coin, the theoretical probability of head is 1/2.
Common Mistakes to Avoid
Tossing two coins has only three equally likely outcomes: two heads, two tails, or one of each.
When a die is thrown, odd and even are the two equally likely outcomes, so each has probability 1/2 without checking the six faces.
A complementary event means simply 'the other event' even if the two events do not cover all outcomes or overlap.
