[LEC4] Flashcards
A subset of the set of all possible outcomes of a probabilistic experiment.
In probability studies, __________ are represented by uppercase
Event
Results of an observation or experiment, or the descriptor of some potential outcome
Event
The measure of the likelihood of an event happening.
Probability
Measures the certainty of an event.
Probability
The _____________ of two events is read as _____________. This means that both events must be met for it to count as one value.
Intersection (A B)
Both A and B
The _________ of two events is read as “_______________ or _________”
Union
Either A or B or both A and B
The ____________ of an event is read as “_______’. This means that the non-fullfillment or the converse/opposite event of A is the trigger for this operation.
Complement
the area within the rectangle box represent all the outcomes called the
sample space
Represents all the outcomes that could possible occurs
Sample space
Sample Space Formula
P(S) = 1
An events that can never occur and has a probability of zero, whereareas most events have probabilities between the value 0 and 1.
Null Event
When two events are mutuall exclusive, the additive rule of probability states that either of the two events will occur is equal is to the sum of the probabilities of the individual events.
Additive Rule of Probability
A type of probability wherein the probability of one event is directly influenced by the probability of another event.
Probability
This is expressed as P (A|B) wherein the probability of an event A is influenced by the existence of event B.
Conditional Probability
Fundamental rule relating marginal probabilities to conditional probabilities. It expresses the total probability of an outcome which can be realized via several distinct events.
Total Probability
