Probabilities

A number that tells how likely an event is to happen.

• probability

• outcome

• event

• simulation

100% probability

• certain

• likely

• unlikely

• uncertain

Something you do over and over again, and you don't know what will happen each time

• my homework

• outcomes

• chance experiment

• events

List of every possible outcome

• chance experiment

• probability model

• simulation

• sample space

A spinner is divided into 4 equally sized selections. The sections are blue, green, red, and yellow. The results of 1000 spins are shown in the table.

What is the experimential probability of spinning a green? (use a reduced fraction)

Vy is shopping for a car. It comes in red, blue, or silver. She can also choose a 2-door and 4-door version along with a manual or automatic transmission. What is the theoretical probability that Vy will pick 4-door car, automatic transmission and it being red or blue?

One of the things that can happen in a chance experiment

• random

• sample space

• outcome

• event

Which would be best to use for an experiment that will produce one of ten different outcomes with equal probability for each.

• standard number cube

• spinner with 10 equal parts

• coin

• bag with 100 pieces of paper

Which is the sample space for the results of opening a book with 428 pages to a specific page?

• All the numbers from 1 to 428

• 1/428

• 1/2

• 0.2%

What is the probability of opening a book with 428 pages in it to page 45?

• the numbers 1 to 428

• 1/428

• 1/2

• 45/428
