Question
A die was thrown 10,000 times. The number "4" showed up 200 times. Which of the following could be TRUE?I. Experimental probability of obtaining the number "4" from a throw = 0.02.II. Theoretical probability of otaining the number "4" = 1/6.III. The die is not a fair die.
Solution
I. TRUE - The experimental probability is calculated as the number of times an event occurs divided by the total number of trials. In this case, the number "4" showed up 200 times out of 10,000 throws. So, the experimental probability is 200/10,000 = 0.02.
II. TRUE - The theoretical probability of obtaining any given number from a single throw of a fair six-sided die is 1/6. This is because there are 6 equally likely outcomes (1, 2, 3, 4, 5, 6), and we are interested in 1 of them (4).
III. POSSIBLY TRUE - The experimental probability (0.02) is lower than the theoretical probability (1/6 or approximately 0.167). This could suggest that the die is not fair. However, we cannot definitively conclude this from a single experiment. It's possible that this discrepancy is due to chance. More trials or statistical testing would be needed to make a stronger claim about the fairness of the die.

Suppose Joan has a fair four-sided die with sides that are numbered 1, 2, 3, and 4.Image attribution: CC BY NC 3.0 by CK-12After she rolls it 2,000 times, she finds that she rolled the number 2 a total of 187 times. Which of the following is true? Joan has provided evidence that calls into question whether or not this is a fair die because the relative frequency of rolling a 2 is quite different than the theoretical probability even after repeating the experiment many times. Joan has demonstrated that this is a fair die, since the relative frequency of rolling a 2 is nearly equal to the theoretical probability. We cannot draw any conclusions from Joan’s experience with this die without also knowing how many times the other numbers appeared. We cannot draw any conclusions from Joan’s experience with this die because there is only a very weak link between the relative frequency of an event and the theoretical probability.
A fair dice is rolled 100 times, and a one is rolled every time. There is a 1/6 chance of rolling any number. What is the most likely outcome of the 101st dice roll? 1 2 3 4 5 6 All are equally likely
