Probability Likelihood

If A and B are independent events, then:

• The probability of B is affected by whether A happens

• A and B cannot both happen

• The probability of A is lower if B happens

• The probability of B is not affected by whether A happens

This type of probability describes the liklihood of something occuring.

• theoretical probability

• experimental probability

People express probability as...(check all that apply)

• fraction

• percentage

• decimal

• integers

Only one possible outcome for an event

• sample space

• simple event

• compound event

• theoretical probability

The set of all possible outcomes of an experiment

• sample space

• event

• experiment

• results

Are two events which do not affect the outcome of each other.

• Equally Likely Events

• Dependent Events

• Probability of Events

• Independent Events

Events in which one event affects the outcome of another

• theoretical probability

• dependent events

• independent events

• sample space

An event is

• a result you could get in an experiment

• the set of all possible outcomes

• a set of one or more outcomes

• the liklihood ngsomething happening

The likelihood of an event happening is _________.

• percentage
