To get this probability, we simply add up the items in the column named Joe.
These items are:
Joe: 34 and 70
And the total is:


The overall population of the system is:

So:


Solving (a): P(Joe and North Side)

Velocity is how fast it moves and in what direction it moves in.
Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.

Hope this helped!
