What is the probability of landing on the blue or red parts of the spinner?
Problem A spinner is a math tool that can be used to demonstrate the probability of a particular outcome. For example if you design a spinner that has a background divided into two equal parts: red and blue, there is a 50\% probability of landing on red and a 50\% probability of landing on blue.
What is the probability of the spinner landing on a number less than 3?
There are 6 total possible results, so the probability of rolling a number less than 3 is 26 or 13 or 0.3333 .
What is the probability of the spinner landing on 1 or 3?
The probability of spinning a 1 or a 3 is 2 / 5 .
What is the probability of spinning the spinner and having it land on red?
1 in 4
The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner. Let’s look at some definitions and examples from the problem above.
What’s the probability that you roll a 3 or less?

How does Jason work out his score in the cards?
He has two sets of cards. One set has three red cards, numbered 1, 2 and 3. The other set has four green cards, numbered 4, 5, 6 and 8. Jason chooses a red card and a green card at random. He works out his score by adding the numbers on the two cards together.
What is Jeff going to spin each spinner?
Jeff is going to spin each spinner once. Each spinner will land on a number. Jeff will get his score by adding these two numbers together. (a) Complete the possibility space diagram for each possible score. [2] Jeff spins each spinner once. (b) Find the probability that Jeff gets (i) a score of 3 (ii) a score of 5 or more.
How many numbers are there on the spinner?
• There are eight equal sections, each showing one number. • There are three different numbers on the spinner. • The probability of the spinner landing on an even number is greater than the probability of it landing on an odd number. • It is more likely that the spinner will land on a 6 than either of the other numbers.
