You can put this solution on YOUR website! If a ball is drawn at random from a container that consists of 40 balls numbered 1 through 40, find the probability that the number drawn is divisible by 4 or divisible by 6. How do I solve this
-------
Divisible by 4:: 4,8,12,16,20,24,28,32,36,40-----10 numbers
-----
Divisible by 6:: 6,12,18,24,30,36--------6 numbers
-----
Note:: 12,24,36 are in both lists
-----
So, # of ways to succeed:: 10+6-3 = 13
----
# of possible selections:: 40
====
P(divis by 4 or 6) = 13/40
