answer the question based on the image posted. if kelly spins the spinner 120 times, how many times would you predict the spinner lands on pink based on experimental data? show your work in the box below the image. color frequency purple 12 pink 6 yellow 9 blue 13
Answer
Explanation:
Step1: Calculate total frequency
$12 + 6+9 + 13=40$
Step2: Find experimental - probability of landing on pink
The experimental - probability $P$ (pink) is $\frac{\text{Frequency of pink}}{\text{Total frequency}}=\frac{6}{40}=\frac{3}{20}$
Step3: Predict number of times landing on pink in 120 spins
Multiply the total number of spins by the experimental - probability. So, $120\times\frac{3}{20}=18$
Answer:
18
