The spinner is divided into 3 equal parts. Use a tree diagram to find the number of possible outcomes when the pointer on the spinner is spun twice
Cannot diagram on these posts.
To construct a tree diagram for this problem, start by drawing a vertical line representing the first spin. Then, branch out three lines from the line to represent the three equal parts of the spinner. Label these lines as 1, 2, and 3, representing the three possible outcomes of the first spin.
From each of these lines, draw an additional three lines to represent the second spin. Label these new lines 1, 2, and 3 as well, again representing the three possible outcomes of the second spin.
At the end of each new line, you will have a total of nine branches representing all the possible outcomes of spinning the pointer twice.
Alternatively, you can use a multiplication principle to find the number of possible outcomes. Since there are 3 possible outcomes for the first spin and 3 possible outcomes for the second spin, the total number of possible outcomes is found by multiplying these numbers together: 3 × 3 = 9. Therefore, there are 9 possible outcomes when the pointer on the spinner is spun twice.
