Question

A spinner is divided into 4 equal - size sections. The sections 4 are red green orange and blue. If Joana spins the spinner twice what are the possible outcomes

Answer 1

RR RG RO RB

GG GR GO GB

OO OR OG OB

BB BR BG BO

There are 16 possible outcomes.

Explanation:

For this question, we combine the possibilities together.

R = red G = green O = orange B = blue

There are 16 possible outcomes.

You can also find the total number of possible outcomes by using the formula for permutations. n is the total number of choices. r is the number you are examining.

`(n!)/((n-r)!)`

`(4!)/((4-2)!) =12`

This number doesn't include the outcome of having the same color twice. There are four colors meaning that their four outcomes in which the same color is spun twice.

12 + 4 = 16
