Study Notes

Probability

Probability is a numerical measure between 0 and 1, representing the likelihood of an event occurring.
0 indicates an impossible event.
1 indicates a certain event.
Values between 0 and 1 represent the degree of likelihood.

Random Experiments

Examples of random experiments include tossing a coin, rolling a die, and selecting a card.

Sample Space

The sample space is the set of all possible outcomes for a given experiment.
For example, flipping a coin has a sample space of {Heads, Tails}, while rolling a die has a sample space of {1, 2, 3, 4, 5, 6}.
