5 faces
The polyhedron is a Triangular Prism.
4 remainder 1 because six goes into twenty-five four times which is twenty-four and one more will make twenty five
when coin is flipped 5 times probability is 1/2
so coin heads comes out to be 2.5
This is a binomial distribution with a probability of success = 0.5 (fair coin).
n=10
so
mean = E[x] = np =10*0.5 =5
