1.The numbers 4 through 14 are placed in a
bowel and drawn at random then replaced
after being drawn. What is the probability of
drawing the number 14 and then a number
less than 12?

2.There are 45 men on the roster of the football
team. 3 are quarterbacks, 10 are offensive
lineman, 6 are defensive lineman. 4 are
running backs, 6 are linebackers, 8 are
defensive backs, 1 is a kicker and the rest are
receivers. What is the probability that out of
two players chosen at random they would be
a QB and a receiver?

3.In a deck of 52 playing cards, what is the
probability of drawing a 3 of spades and then
a 4 of spades?
 
These are counting problems and exercises in understanding independence.

How many 14s are in the bag? How many total items are in the bag?
