I am having trouble trying to solve uniform distribution questions like these in paper June 2007 Edexcel.
I can't pinpoint what the boundaries will be and I thought that it would be -5,5

A string AB of length 5 cm is cut, in a random place C, into two pieces. The random
variable X is the length of AC.
(a) Write down the name of the probability distribution of X and sketch the graph of its
probability density function.

Its a length so >=0 and the piece cannot be longer than original string so {0,5} would be the boundaries.
