Study Notes
Combinatorics and Probability
- Maximum value of k when picking k elements from an n-element set is n.
Sampling
- Sampling type considered in the scenario: Without replacement.
Coin Toss Probability
- Probability of getting exactly 1000 heads when tossing a fair coin a thousand times: Extremely low (approaching zero).
- Probability of getting exactly 500 heads when tossing a fair coin a thousand times: Highest probability (around 0.025).
Counting Ways
- 'Count the number of different ways to do this' means counting the number of permutations or combinations.
- When picking 2 elements from an n-element set, the number of different ways they can be picked, considering the order, is n × (n - 1).
