Asked by David

A study has shown that the thickness of
sheet steel follows an approximately
uniform distribution from 20 to 50mm.
What is the probability that a sheet of steel chosen at random will be between 20 and 30mm?

Answered by PsyDAG
If uniform means the same frequency for all thicknesses, then 20-30 is 1/3 of the range from 20-50.

Does that help?
