    i actually need help on this one :) )A six-sided number cube labeled 1 through 6 is rolled 200 times. An even number is rolled 115 times. Compare the theoretical probability of rolling an even number with the relative frequency of rolling an even number and select one of the statements below that best describes the situation. The theoretical probability and relative frequency are the same. The theoretical probability is larger than the relative frequency. The theoretical probability is smaller than the relative frequency. There is not enough information to determine the relative frequency.

    Looking at the second problem you posted "the six sided number cube" and comparing the theoretical probability.

    @jtvatsim i need the answer for that question please! :)

    Alright, so think about it this way. Theoretically speaking, we have 3 even numbers (2, 4, 6) on the number cube. But, there are 6 numbers on the cube total (1 thru 6). This means we would expect to get an even number 3/6 of the time. Simplified, this is about 50%. However, what we actually saw (the relative frequency) was 115/200. This is 57.5%. So, theoretical probability = 50% and relative frequency = 57.5%. You can probably figure out the correct answer from here. :)

    thanks! i have more :) Eddie believes that if he flips a coin 650 times, it will land heads up exactly 325 times. What would you tell Eddie about his prediction?

    Well, what do you think? Do you believe that you will get heads EXACTLY half of the time? Think about the last question we answered too. :)

    i think his prediction is wrong

    Yes, you are probably right. It is unlikely that we will get exactly half of the tosses to be heads. This is the theoretical probability. But, the relative frequency (what we actually observe) might be slightly different. The relative frequency tends to APPROXIMATE the theoretical probability. But is rarely EXACTLY the same. Good thinking. :)

    I think something along the lines of what I said above. That should suffice.

    I disagree for the first question, it would be certain not likely

    for the 25/25 question

    Well if something happens 25 times out of 25 times.... that's 100% of the time that it happens... :)

    @heretohelpalways So, I think you are exactly right. It is certain to happen. It happens all the time. :)
