    This is great! Soon taking a course on probabilistics, and some of these can sure help. You do sound a bit tired though Sal.

      Kosmic Kiwi Oooof I have a test tomorrow on this and since our original teacher left to have the baby, we had a substitute teacher who didn't explain A THING.. so now I HAVE TO TEACH MYSELF PROBABILITY AT 2 AM BECAUSE I REALIZED IM GONNA FAIL THIS TEST IF I DONT TEACH MYSELF

    Im still unclear about what the difference between theoretical and experimental probabilities is.

    • @sarapetkovic7823
      @sarapetkovic7823 8 лет назад +19

      Theoretical is what the theory tells you and the experimental is when you actually do the experiment and get your own results.

    • @camrenmcfadden6911
      @camrenmcfadden6911 7 лет назад +1

      Barbod Nikzad experimental is what physically happens and theoritcal is what should happen sorry for spelling

    • @harwinderthind3569
      @harwinderthind3569 7 лет назад +1

      Theoretical is a theory you make about the answer from the facts you have (what should happen)and experimentally is the the outcome (what actually happened)

  • @jamestill4172
    @jamestill4172 3 года назад

    Need help understanding the difference? It is theoretical (should be 50%) before it is experimental (it was 70%). Theoretical is pure reason (while subjective is guessing), and experimental is when you experiment to find the solution.

    • @jamestill4172
      @jamestill4172 3 года назад

      Theoretical: Flipping a coin should result in heads 50% of the time
      Experimental: I have flipped the coin 10 times, and it landed on heads 5 times.

    Please explain...?

    • @Roleplayer40K
      @Roleplayer40K 9 лет назад

      It has to do with circumference. The circumference of a circle is calculated by Diameter multiplied by Pi.
      Since it isn't very regular that you use Diameter when you go into more advanced math (you usually use Radius), you use 2 Pi because multiplied with the Radius it give the cirumference.

    • @lentmain
      @lentmain 9 лет назад

      Gaztinerag Thank you for the info... I can more easily see things when they have a rational approach... 2 pi rr is the circumference formula... Now if I could get the jest of Sine and cosine... More reading.... Thank you again...

      because of luck? for example even if you have a probability of getting magenta, blue, magenta, blue it is not guranteed and you'd get something like magenta magenta blue magenta

    @HeliosPlayz 4 года назад

    Summing up a video when you are doing probability with something like flipping a coin or picking a color (of 2) out of a bag of you keep trying 100 times even 1million you will eventually get half but it could even take a a long time depending on how much time you have
