Question

use the spinner to determine who will order first.
use the interactive spinner to model who among elisondra and her three friends will order first. then answer the questions.
what is the theoretical probability of the spinner landing on elisondras section?
spin the spinner. who orders first?

Explanation:

Step1: Determine the number of sections

The spinner is divided into 4 equal - sized sections (for Elisondra, Raquel, Sarah, and Diya). So, \(n = 4\).

Step2: Calculate the probability formula

The formula for theoretical probability is \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\).
For the spinner landing on Elisondra's section, the number of favorable outcomes \(m = 1\) (since there is 1 section labeled Elisondra), and the total number of outcomes \(n = 4\).
So, \(P=\frac{1}{4}\)

Answer:

The theoretical probability of the spinner landing on Elisondra's section is \(\frac{1}{4}\)
