Simple Probability Experimental and Theoretical

The number of ways an event can occur divided by the total number of outcomes is known as - 

• an event complement

• experimental probability

• an event

• theoretical probability

The ratio of the number of times an event occurred compared to the total number of trials conducted is known as - 

• theoretical probability

• experimental probability

• simple probability

• compound probability

A set of all possible outcomes is known as - 

• a list

• a complement

• a sample space

• an event

In probability theory, the sum of an event (A) occurring and the same event NOT occurring (not A) is always - 

• 0

• based on the sample space

• variable

• 1

P(A) + P(not A) = 1

• True

• False

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

If a coin is tossed 3 times, how many possible outcomes are in the sample space?

• 6

• 8

• 3

• It depends

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

• tree diagrams

• area models

• organized lists

• guess and check

When collected data is used to express probability, we call it - 

• theoretical probability

• experimental probability

• simple probability

• compound probability
