Each person will shake hands with 4 other people, thus there will be a total of 20 handshakes among the 5 people in the room.

A handshake is defined by picking 2 people to shake hands out of the group of 5. The number of ways you can pick a subset of 2 objects from a set of 5 is 5!/2!3! = 10

B shakes hands with C, D & E = 3 handshakes
C shakes hands with D & E = 2 handshakes
D shakes hands with E = 1 handshake
4+3+2+1=10

It's 10 handshakes total. Once one person shakes the other four... that person is done shaking. Move him out of the room. That leaves four. One person shakes the other remaining 3 handshakes and moves out. That leaves 3 in the room. One then shakes 2 hands and moves out of the room...and it continues from there. 10 total shakes!

Person 5 shakes hands with 4 3 2 1
Person 4 shakes hands with 3 2 1
Person 3 shakes hands with 2 1
Person 2 shakes hands with 1
Therefore there are ten handshakes.
