To model radioactive decay you need to generate random numbers that have an exponential distribution. To find out how see

Radioactive decay is usually simply modelled by constructing a graph of the half life

You use a semi- logarithmic plot
It is a plot where the abscissa has a usual scale but the ordinate has a logarithmic scale . in this type of plot, the radioactive decay is represented as a straight line. and you can evaluate the half-time by the slope

Get a well thermally insulated hot metal bar with a small drilled hole in it and measure its rate of cooling by means of a thermocouple.Plot and analyse the results over a few hours,you'll probably need to ignore the first 10minutes of readings.

By what is called 'exponential decay'. Look it up on the web.

Meg is right. You could also try looking up 'Monte Carlo Methods'.

m(t)/m0=a million-0.seventy two (because of the fact the proportion left is the same because of the fact the ratio of the unique to the present pattern) so...0.28=e^(-t*ln(2)/h) ln(0.28)=-t*ln(2)/h -30*ln(0.28)/ln(2)=t t=55s
