Question

Irene has a spinner with 5 sections, each with a different color. Irene spins the spinner many times, and records the results in the table.

Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10


Find the probability of spinning each color, based on the data. Explain how you calculated each probability.

Answer 1

Explanation:

Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.

Total frequency = 16 + 11 + 9 + 14 + 10 = 60

Hence we have the following probabilities:

• P(Red) = 16/60 = 4/15
• P(Orange) = 11/60
• P(Yellow) = 9/60 = 3/20
• P(Green) = 14/60 = 7/30
• P(Blue) = 10/60 = 1/6
