Answer:
1000
Step-by-step explanation:
The theory is that <em><u>"experimental probability goes closer and closer in value to the theoretical probability as the number of trials increase."</u></em>
So <em>more trials means more they are closer and equivalent.</em>
So out of the answer choices, the largest number of trials is 1000.
1000 is the correct answer.
The solution for this question is simple. First we need to divide both numbers by 2 which will give us 10 and 7. This is the equation x^2/10^2 + y^2/7^2 = 1sqrt(100-49) = 7.14 (the answer do not have a perfect square root)
