Pelle has 3 different bags of bullets, answer the three questions below. Remember to explain how you arrive at the answers:

1. Calculate the probability that you draw two red balls in a row out of a bag with 2 blue, 5 red and 3 yellow balls, the only difference between the balls is the color. The first ball is put back in the bag before the second is drawn.

2. In the other bag there are 5 purple, 7 orange and 9 brown balls, the only difference between the balls is the color. You should pull three balls out of the bag, each drawn ball is placed on the table. What is the probability that after you draw your three balls, one of each color has on the table?

3. The third bag is very large and contains one million bullets. We draw 100 randomly selected balls, of which 70 are red and 20 yellow and 10 white. What can we say about all the balls and their color?
