Jamie rolls a 6-sided die 30 times and determines that the experimental probability of rolling a 2 is 1/15. the theoretical probability of rolling a 2 is 1/6 what could jamie do to make his experimental results more closely match the theoretical probability?
a. he can increase the number of trials.
b. he can decrease the number of trials.
c. he can increase the number of sides on the die.
d. he can decrease the number of sides on the die.

Theoretical Probability is what you expect to happen whereas Experimental Probability is what actually happens.

Probability is calculated same way for both, dividing the number of possible ways an outcome can occur divided by the total number of outcomes.

Experimental probability gets closer and closer to the theoretical probability as more and more trials are conducted.

So, Jamie should increase the number of trials to make his experimental probability results closer to the theoretical probability result. Answer choice A is correct.

ANSWER: A

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
