Challenge Level

Given a probability density function find the mean, median and mode of the distribution.

Challenge Level

Can you work out the means of these distributions using numerical methods?

Challenge Level

Invent scenarios which would give rise to these probability density functions.

Challenge Level

By exploring the concept of scale invariance, find the probability that a random piece of real data begins with a 1.
