Relative Frequency Worksheet

Relative Frequency Practice

Read each question carefully and provide the best answer. Show your work where applicable.

1. What is relative frequency and how is it different from theoretical probability?

A coin was flipped 50 times. It landed on heads 28 times and tails 22 times.

2. The relative frequency of landing on heads is  .

3. The relative frequency of landing on tails is  .

4. A spinner has 4 equal sections: Red, Blue, Green, Yellow. If you spin it 100 times and it lands on Red 30 times, what is the relative frequency of landing on Red?

A bag contains marbles of different colors. You draw a marble, record its color, and replace it. You do this 40 times. Here are your results:

Red: 15 times

Blue: 10 times

Green: 8 times

Yellow: 7 times

5. Calculate the relative frequency for each color. Express your answers as decimals.

Red:  

Blue:  

Green:  

Yellow:  

6. Based on the data from question 5, if you were to draw a marble 100 more times, how many times would you predict it to be Blue? Explain your reasoning.
