Question 18

A student uses 40 standard six-sided dice to model the radioactive decay of a sample of nuclei.

They carry out the following method:

  1. Roll all 40 dice at the same time.
  2. Remove any dice that land on a '6' (representing decayed nuclei).
  3. Record the number of remaining dice.
  4. Roll the remaining dice.
  5. Repeat this process five more times.

State two improvements the student could make to this experiment to obtain more reliable or representative data.
