Experimental Probability Worksheets Grade 7

1. A school is conducting a survey about favorite school subjects. In a random sample of 120 students, 45 students chose math as their favorite subject. Based on this sample, approximately how many students out of the entire school of 800 students would you expect to choose math as their favorite subject?
2. Liam is testing a new board game that uses a spinner divided into 7 equal sections numbered from 1 to 7. He spins the spinner 11,000 times and records the results in a bar graph. The bar for each number is described below: - Number 1: height of 1,573 - Number 2: height of 1,571 - Number 3: height of 1,575 - Number 4: height of 1,569 - Number 5: height of 1,577 - Number 6: height of 1,565 - Number 7: height of 1,570 Based on Liam's experimental data, what is the approximate probability that the spinner will land on an odd number? Express your answer as a decimal rounded to the nearest thousandth.
3. A school is conducting a survey about favorite school subjects. In a random sample of 120 students, 45 students selected mathematics as their favorite subject. If the school has 800 students total, approximately how many students would you expect to have mathematics as their favorite subject?

1. A school is conducting a survey about favorite after-school activities. In a random sample of 120 students, 45 students chose sports, 30 chose music, 25 chose art, and 20 chose reading. If the school has 800 students total, based on this sample, approximately how many students would you expect to choose sports as their favorite activity?
2. A school is conducting a survey about favorite school subjects. In a random sample of 200 students, 45 students chose mathematics as their favorite subject. Based on this sample, approximately how many students would you expect to choose mathematics as their favorite subject if the entire school has 1,240 students?
3. 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.
