Simple and Compound Probability and Tree Diagrams

Which of the following expressions can be used to calculate the probability of two related events occurring?

• P(event) x 2

• P(event 1) +   P(event 2)

• P(event 1) x     P(event 2)

• P(event 1 + 2)

The likelihood that an event will NOT occur is known as its - 

• complement

• sample space

• opposite

• trial

Which of the following methods is NOT a good tool for determining sample space?

• tree diagrams

• area models

• organized lists

• guess and check

A measurement of the likelihood of an event or events occurring on a scale of 0 to 1 is called - 

• data

• luck

• probability

• trials

In compound probability, if one event does not affect the other event or events, it is referred to as - 

• theoretical probability

• independent probability

• experimental probability

• dependent probability

In compound probability, if one event affects another event we call it - 

• independent probability

• experimental probability

• simple probability

• dependent probability

A set of all possible outcomes is known as - 

• a list

• a complement

• a sample space

• an event

The probability of an event occurring, P(A), can be expressed as a fraction, decimal, or percent.

• True

• False

Select all the situations that are compound events.

• Tossing a coin and rolling a die

• P(red or even)

• P(red and even)

• Tossing a coin twice in a row

• Getting even on a die
