math

• branch of mathematics that deals with uncertainly: probabilty
• measure of how likely the event will happen: probability
• 0% chance to happen: impossible
• 1/4, 0.25, 25% chance to happen: unlikely
• 50/50, 1/2, 0.5, 50% chance to happen: even chance
• 3/4, 0.75, 75% chance to happen: likely
• 100% chance to happen: certain
• set of all possible outcomes of a random experiment is called: sample space
• one of the possible outcome any element in sample space: sample point
• is any set of one or more outcomes satisfying some given conditions, it is a subset of sample space ex: getting a head: event
• difference of sample space and outcome: sample space is the set of all possible outcomes, outcome is the single result of an experiment
• process that has a number of possible outcomes by which an observation is obtained: experiment
• a set whose elements are obtained depending on the given conditions: event
