  • Q1

    If you roll a number cube 3 times. You repeat that action 10 times. Which set of results do you think is most likely to happen? 

    Question Image

    Set 3 -because it is uneven so it seems more real

    No Set- none of these could actually happen

    Set 2- because it is random

    Set 1 - because it is balanced

    The \frac{8}{12} chance of getting  2 "N's"

    The \frac{1}{2} chance of getting a random "D" or "N"

    The \frac{4}{12} chance of getting a "D" and an "N"

  • Q10

    With one roll of the two number cubes shown here the total was eight. What is the probability of rolling a total of 3?

    Question Image

    It is not possible as 3 is an odd number and you have two dice.

    \frac{1}{18}

    \frac{4}{36}

    \frac{2}{18}
