Can you work out the means of these distributions using numerical methods?
When is an experiment described by the binomial distribution? Why do we need both the condition about independence and the one about constant probability?
This article explores the process of making and testing hypotheses.
Are these scenarios described by the binomial distribution?
Can you create random variables satisfying certain conditions?
This tool allows you to create custom-specified random numbers, such as the total on three dice.
Typical survey sample sizes are about 1000 people. Why is this?
This article offers an advanced perspective on random variables for the interested reader.
When five dice are rolled together which do you expect to see more often, no sixes or all sixes ?
