Question

use the interactive spinner to simulate who among ellison dra and her three friends will order first during 40 restaurant visits. if the theoretical probability of sarah ordering first is 0.25, what is the experimental probability of sarah ordering first? experimental probability: p(sarah) = \frac{observed frequency}{number of trials} =

Explanation:

Step1: Recall the formula for experimental probability

Experimental probability formula is \( P(\text{event})=\frac{\text{Observed frequency of the event}}{\text{Number of trials}} \).

Step2: Identify the number of trials

Here, the number of trials is the number of restaurant visits which is \( 40 \).

Step3: Substitute into the formula

For the event of Sarah ordering first, using the formula \( P(\text{Sarah})=\frac{\text{Observed frequency of Sarah ordering first}}{\text{Number of trials}} \), and since number of trials \( = 40 \), we get \( P(\text{Sarah})=\frac{\text{Observed frequency of Sarah ordering first}}{40} \).

Answer:

\( \frac{\text{Observed frequency of Sarah ordering first}}{40} \)
