The experimental probability of a sunflower seed germinating is 30 out of 40, or 3/4.
To approximate the number of seeds that will germinate if you sow 20 seeds, you would expect 3/4 of them to germinate.
Therefore, the approximate number of seeds that will germinate if you sow 20 seeds is 15.
So the answer is 15.
You sow 40 sunflower seeds, and 30 of them are germinated. Use experimental probability to approximate the number of seeds that will germinate if you sow 20 seeds?(1 point) Responses 30 30 15 15 40 40 34 Start Fraction 3 over 4 End Fraction

A survey was conducted of 300 people to see if they were right or left hand dominant. After carrying out the survey, 30 participants reported themselves as being left-handed, while 270 people reported themselves as being right-handed. Using these results, which of the following statements is true? (1 point) Responses The experimental probability that a person is right-handed is greater than the theoretical probability. The experimental probability that a person is right-handed is greater than the theoretical probability. The experimental probability that a person is right-handed is equal to the theoretical probability. The experimental probability that a person is right-handed is equal to the theoretical probability. The experimental probability that a person is right-handed is 50. The experimental probability that a person is right-handed is 50. The experimental probability that a person is right-handed is less than the theoretical probability.
The theoretical probability of a person being right-handed is calculated as the total number of right-handed people divided by the total number of people surveyed:
Theoretical Probability = 270 (right-handed) / 300 (total surveyed) = 9/10 = 0.9
The experimental probability of a person being right-handed is calculated based on the survey results:
Experimental Probability = 270 (right-handed) / 300 (total surveyed) = 9/10 = 0.9
Comparing the theoretical and experimental probabilities, we can see that they are equal.
Therefore, the correct statement is:
"The experimental probability that a person is right-handed is equal to the theoretical probability."
Theoretical Probability = 270 (right-handed) / 300 (total surveyed) = 9/10 = 0.9
The experimental probability of a person being right-handed is calculated based on the survey results:
Experimental Probability = 270 (right-handed) / 300 (total surveyed) = 9/10 = 0.9
Comparing the theoretical and experimental probabilities, we can see that they are equal.
Therefore, the correct statement is:
"The experimental probability that a person is right-handed is equal to the theoretical probability."
