Terms in this set (...)

complementary events
two disjoint events that together make up the entire sample space
P(at least 1)
1- P(none)
mutually exclusive events (disjoint events)
events that can't happen at the same time
A ∩ B
A intersect B; the outcomes that are in A and that are also in B
Independent events
the probability of one occurring does not affect the probability of the other; P(A) = P(A|B)
The Law of Large Numbers
As the number of trails increases, the proportion of times a specific outcome occurs approaches a single value
outcome
the possible result of a situation or experiment
event
a single outcome or a group of outcomes
sample space
the set of all possible outcomes
probability
the numerical value from 0 to 1 that measures the likelihood of an event;
P(event) = (number of favorable outcomes) ÷ (number of possible outcomes)
trial
in probability, a single repetition or observation of an experiment
probability model or probability distribution
identifies all possible outcomes and the corresponding probability of each possible outcome
A ∪ B
A union B; ; the outcomes that are in A or B (or both)
conditional probability, P(A|B)
The probability that A occurs, given that B has occurred
