Chapter 5 - Probability Flashcards
probability
a measure of the likelihood of a random phenomenon or chance behavior.
p259
outcome
A certain result that occurs after an experiment.
p259
The Law of Large Numbers
As the number of repetitions of a probability experiment increases, the proportion with which a certain outcome is observed gets closer to the probability of the outcome.
p259
experiment
any process with uncertain results that can be repeated.
p260
sample space
S, the collection of all possible outcomes in a probability experiment.
p260
event
any collection of outcomes from a probability experiment.
p260
probability model
lists the possible outcomes of a probability experiment and each outcome’s probability.
p261
impossible event
an event whose probability is 0.
p261
certainty
an event whose probability is 1.
p261
unusual event
an event that has a low probability of occurring.
p261
equally likely outcomes
Each outcome has the same probability of occurring.
p263
tree diagram
lists the equally likely outcomes of the experiment.
p265
subjective probability
a probability obtained on the basis of personal judgment.
p268
disjoint
When two events have no outcomes in common. In other words two events are disjoint if they cannot occur at the same time.
p274
mutually exclusive
or disjoint (see disjoint)
