Question

the results of a color spinner experiment are shown in the table. consider the experimental probability of the spinner landing on green. if the experiment is repeated with 50 spins, what is the prediction for the number of spins that will land on green?

result	frequency
red	9
green	6
yellow	8

5
6
10
12

Explanation:

Step1: Calculate total spins in first experiment

$7 + 9+6 + 8=30$

Step2: Calculate experimental probability of landing on green

The experimental - probability $P(\text{green})=\frac{\text{Frequency of green}}{\text{Total spins}}=\frac{6}{30}=\frac{1}{5}$

Step3: Predict number of green - landings in 50 spins

Multiply the probability by the number of spins. So, the predicted number of spins landing on green is $\frac{1}{5}\times50 = 10$

Answer:

10
