Need a bit of help with this one. I have tried my best to look through all the notes we were provided however I can seem to figure this one out.
a) I roll a six-sided dice 15 times and average the results, what is the approximate probability that the average will be more than 4.2 (i.e. exceeding the 60% percentile)
b) Now I roll it 45 times, do you expect the chance will be higher, lower, or the same? What is the new probability
c) What about a single die roll? (beware cognitive inertia)
Thanks in advance!!!
