Outcome Probability

Probability is defined as...

• the set of all possible outcomes.

• the likelihood that an event will happen.

• the fundamental counting principle.

Which method is used in an experiment that shows the outcome like a tree?

• Table

• Tree Diagram

• Systematic Listing

• Fundamental Counting Principle?

When rolling 1 die once, spinning a spinner once, and flipping a coin once, how many combinations are possible?

• 13

• 60

• 32

• 16

Tree diagrams are useful because...

• they are cool to draw.

• they only show you the best choices.

• they show you all possible outcomes.

Unequally likely is

• different possible outcomes

• outcomes that have the same chance of occuring

• outcomes that don't have the same chance of occuring

•  the favorable outcome

The result of an experiment is a(n)​ (a)  

• Outcome

• equally likely

• simple event

• complementary events

• Experiment

A(n) (a)   ​ is one or a group of possible outcomes for a given situation.​

• Event

• Experiment

• Probability

• Equally Likely

• Outcome

• Sample Space

• Simple Event

• Complementary Events

The square spinner shown is spun twice, and the results of the two spins are multiplied together to produce a product that is recorded.

Are all outcomes equally likely?

​ (a)   , the outcomes ​ (b)   equally likely.

• No

• aren't

• Yes

• are

• We don't know

• can't tell us if they are

The theoretical probability of an even happening can be written as the number of ​ (a)   over the number of ​ (b)   .

• favorable outcomes

• possible outcomes

• favorite outcomes

• worst outcomes

• total trials

20% of the boxes shown contain only 1 gold coin each.

60% of the boxes shown contain only 1 silver coin each.

All remaining boxes are empty EXCEPT for one,

which contains 1 million dollars.

How many boxes are empty?
