c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is drawn at random. Find the probability of this ball being a blue ball?  
Question 2
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is drawn at random. Find the probability of this ball not being a green ball?  
b: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is drawn at random. Find the probability of this ball not being a red ball?  
c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is drawn at random. Find the probability of this ball not being a blue ball?  
Question 3
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. When you draw 2 balls from the bag, what is the probability that you get a green and a red ball?  
b: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. When you draw 2 balls from the bag, what is the probability that you get a green and a blue ball?  
c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. When you draw 2 balls from the bag, what is the probability that you get a red and a blue ball?  
Question 4
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is taken from the bag, then replaced. Then another ball is taken from the bag. What is the probability of choosing a red ball and then a blue ball?  
b: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is taken from the bag, then replaced. Then another ball is taken from the bag. What is the probability of choosing a red ball and then a green ball?  
c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is taken from the bag, then replaced. Then another ball is taken from the bag. What is the probability of choosing a blue and then a green ball?  
Question 5
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is selected at random and is not replaced, a second ball is then selected at random. What is the probability that both balls are red? 
b: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is selected at random and is not replaced, a second ball is then selected at random. What is the probability that both balls are blue? 
c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. One ball is selected at random and is not replaced, a second ball is then selected at random. What is the probability that both balls are green? 
Question 6
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is chosen at random from the bag and not replaced; then a second ball is chosen. What is the probability that none of the selected balls is red?  
b: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is chosen at random from the bag and not replaced; then a second ball is chosen. What is the probability that none of the selected balls is blue?  
c: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. A ball is chosen at random from the bag and not replaced; then a second ball is chosen. What is the probability that none of the selected balls is green?  
Question 7
a: A bag contains \[n\] red, \[m\] blue and \[k\] green balls. What is the probability that a red, blue, and green ball may be picked?
