A
A probability between equally likely and impossible is?
unlikely or less than 0.5 and greater than 0
When something will happen, the probability is?
Certain or 1
When something can not happen, it is?
Impossible or 0
A probability of 50:50 is?
Even, equally likely or 0.5
A probability between equally likely and certain is?
likely or greater than 0.5 but less than 1
The Probability of event D occurring is represented by?
P(D)
{Yellow, Orange, Purple} represent?
A sample space of that contains Yellow, Orange and Purple.
P (Brown) = 1
means
Brown is certain
P(blue)=0
means?
blue is impossible
P (red) = 0.2
means?
Red is unlikely
What are mutually exclusive events?
Two or more events are mutually exclusive if they share no outcomes.
What is relative probability?
Relative probability refers to how likely an event is to occur.
What is subjective probability?
This is based on the person's on reasoning or biased.
What is the sum of all probabilities?
The sum of all probabilities of all the outcomes of a chance experiment is 1.
What are non-mutually exclusive events?
Events are non-mutually exclusive if they share one or more outcomes.
What are favourable outcomes?
Outcomes are favourable when they are part of a desired event.
What is a trial?
When an experiment is performed one or more times, each time it is performed it is called a trial.
What is an event?
An event is either one outcome or a collection of outcomes.
What is an outcome?
An outcome is one of the possible results of a chance experiment.
What are equally likely outcomes?
Equally likely outcomes are two or more results that have the same chance of occurring.
What is theoretical probability?
Theoretical probability is the actual chance or likelihood that an event will occur when an experiment takes place.
What is experimental probability?
Sometimes it is difficult or impossible to calculate a theoretical probability, so an estimate can be found using a large number of trials.
What is a chance experiment?
A chance experiment is an activity which may produce a variety of results that occur randomly.
What is a sample space?
The sample space is the set of all possible outcomes of an experiment. It is usually written in braces.
What is a compound event?
A compound event is a collection of two or more outcomes from the sample space of a chance experiment.
