What is the probability of rolling a 5 on a 6-sided die?

I believe this is 1/6 because there is only one 5 on a 6-sided die.

I am stuck on this part of the question:
If you roll the die 6 times, how many 5’s do you expect to get? Would you definitely get this number of 5’s? Explain why or why not.

  1. 1/6 is correct

    6 times, expect 1 five. But this is the average number. All you have to do is roll a die several times to see that it will not happen every time.

    Q: What's the difference between theory and practice?
    A: In theory, there is no difference, but in practice, there is!
