The big clock

The big clock hands stopped at a random moment. What is the probability that:

a) a small hand showed the time between 1:00 and 3:00?
b) the big hand was in the same area as a small hand in the role of a)?
c) did the hours just show the time between 21:00 and 22:30?

Result

p1 =  25 %
p2 =  25 %
p3 =  12.5 %
