Given the mean and standard deviation of a set of marks, what is
the greatest number of candidates who could have scored 100%?
Your data is a set of positive numbers. What is the maximum value
that the standard deviation can take?
This tool allows you to create custom-specified random numbers,
such as the total on three dice.

happens ? What sort of things might be the same ? What might be
When five dice are rolled together which do you expect to see more
often, no sixes or all sixes ?
Use your skill and judgement to match the sets of random data.
