Experimental Probability Worksheets Grade 7

1. Mason rolled a standard six-sided die 200 times and recorded the number 5 appearing 39 times. Approximate P(5).
2. Emma is testing a new game that uses a spinner divided into 4 equal sections: red, blue, yellow, and green. She spins the spinner 500 times and records the results in a bar graph. The bar for red has a height of 135, the bar for blue has a height of 120, the bar for yellow has a height of 145, and the bar for green has a height of 100. Based on Emma's experimental data, what is the approximate probability that the spinner will land on red or green? Express your answer as a decimal rounded to the nearest hundredth.
3. Tane rolled a standard six-sided die 135 times. He recorded the number 3 appearing 27 times. Approximate P(3).

1. Emma is conducting a probability experiment with a spinner divided into 8 equal sections: 3 red, 2 blue, 2 green, and 1 yellow. She spins the spinner 200 times and records the results. If the experimental probability of landing on red is 0.38, how many times did the spinner land on red during her experiment?
2. Emma is conducting a probability experiment with a spinner divided into 8 equal sections labeled 1 through 8. She spins the spinner 200 times and records that it lands on an even number 112 times. Based on her experiment, what is the experimental probability of the spinner landing on an even number? Express your answer as a simplified fraction.
3. (-3)² + 4 × (-5) = ?

1. Emma is conducting a probability experiment with a spinner divided into 8 equal sections: 3 red, 2 blue, 2 green, and 1 yellow. After spinning it 200 times, she records that it lands on red 72 times. Based on her experiment, what is the experimental probability of the spinner landing on red? Express your answer as a simplified fraction.
2. (-4)² - 3 × (18 ÷ 6 + 2) = ?
3. Noah is conducting a science experiment where he drops a marble onto a grid of 10 equal-sized squares numbered 1 through 10. He drops the marble 500 times and records which square it lands in. The results are shown in the bar graph below (described in text): - Square 1: 48 times - Square 2: 52 times - Square 3: 47 times - Square 4: 53 times - Square 5: 49 times - Square 6: 51 times - Square 7: 50 times - Square 8: 52 times - Square 9: 48 times - Square 10: 50 times Based on Noah's experimental data, what is the approximate probability that the marble lands on a square with a number that is a multiple of 3? Express your answer as a decimal rounded to the nearest hundredth.
