1. Core Ideas

P(E) = Number of trials in which the event happened / Total number of trials

Probability = Number of favourable outcomes / Total number of outcomes

P(E) + P(E') = 1

2. Empirical Probability Examples

P(E) = Number of trials in which the event happened / Total number of trials

P(E') = 1 - P(E)

3. Probability from Dice and Survey Data

P(E) = Number of favourable outcomes / Total number of outcomes

4. Complementary Events

P(E) + P(E') = 1

P(E) = 1 - P(E')

P(E') = 1 - P(E)
