Get into the exponential distribution through an exploration of its pdf.
Can you build a distribution with the maximum theoretical spread?
How is the length of time between the birth of an animal and the birth of its great great ... great grandparent distributed?
When is an experiment described by the binomial distribution? Why do we need both the condition about independence and the one about constant probability?
Are these scenarios described by the binomial distribution?
This tool allows you to create custom-specified random numbers, such as the total on three dice.
Use your skill and judgement to match the sets of random data.
How do scores on dice and factors of polynomials relate to each other?
Use the computer to model an epidemic. Try out public health policies to control the spread of the epidemic, to minimise the number of sick days and deaths.
When five dice are rolled together which do you expect to see more often, no sixes or all sixes ?
