Basic Probability - Answer Key

Sep 30, 2026

Uploaded by Aldword

Basic Probability answer key for a worksheet using diagrams to calculate event probabilities with dice, spinners, and shape arrays. It provides solutions for selecting single outcomes such as rolling a 6, not rolling a 1, landing on odd numbers, and spinner results involving black, white, and gray pieces. It also includes probabilities based on total counts of spinner pieces and array shapes, including identifying the most likely shape and a 45.00% selection case.

Basic Probability Name: Use each diagram to solve the problems. 1) If you were to roll the dice one time what is the probability it will landon a 6? 2) If you were to roll the dice one time what is the probability it will NOT land on a 1? 3) If you were to roll the dice one time, what is the probability of it landing on an odd number? 4) If you spun the spinner 1 time, what is the probability of landing on either a black piece or a white piece? 5) If you spun the spinner 1 time, what is the probability it would land on a black piece? 6) If you spun the spinner 1 time, what is the probability it would land on a gray piece? 7) How many pieces are there total in the spinner? 8) If you spun the spinner 1 time, what is the probability it would land on a white piece? 9) How many shapes are there total in the array? 10) If you were to select 1 shape at random from the array, what is the probability it will be a diamond? 11) If you were to select 1 shape at random from the array, what shape do you have the greatest probability of selecting? 12) Which shape has a 45 .00% chance (9 out of 20) of being selected?

FAQs

What is the probability of rolling a 6 in one dice roll?

The answer key gives 1 out of 6.

How is the spinner probability determined for landing on black or white pieces?

The worksheet uses the spinner diagram counts, and the answer key provides the corresponding probabilities such as 6 out of 9 for black or white.

Which shape has the greatest probability of being selected, and what is the 45.00% case?

The answer key states the greatest-probability shape is a diamond, and the shape with a 45.00% chance is also identified as 9 out of 20.
