Consider an experiment consisting of randomly selecting a real number r between 0 and 1. The

sample space is then the interval (0, 1), since the outcome can be any number in this interval.

(a) Find the set A representing the event that r is between 0.3 and 0.4.

(b) Find the set B representing the event that r is between 0.35 and 0.6.

(c) Find the set C' representing the event that r is either less than 0.25 or greater than 0.75.

(d) Find An B.
