Answer:
use the four titles tool,trial,results,calculation.
in tool state what tool you'll be using eg: spinner, computer random number generator, cards, dice etc.
then say what things will represent eg: if you were to use a computer random number generator say use numbers 1-10, 1-6= ....... 7-10=...........
in trial describe 1 trial eg: generate 3 numbers each number represents ....... etc
then state how many times you repeat this eg: repeat 50 times
also state what a successful trial is eg: yes = successful trial
in results you draw up a table of what it should look like
in calulations write number of successful trials/number of trials <--write as afraction
and that's it
