A bag contains 3 balls numbered from 1 to 3. In an experiment, a ball is selected at random from the bag, replaced, and then another ball is selected. How many possible outcomes are there?
Use the Fundamental Counting Principle to find the total number of outcomes of rolling 4 number cubes and tossing 2 coins.
Use the Fundamental Counting Principle to find the total number of outcomes of tossing 11 coins.

Use the Fundamental Counting Principle to determine the total number of outcomes of choosing, with the possibility of repetition, a password that consists of three letters and three numbers from 1 to 7.
Suppose there are 9 sheep whose fur may be only one of two colors, white or brown. Using the tree diagram, determine the total number of possible sheep-color choices.
Suppose two spinners are spun. The first has 5 equal sectors numbered from 1 to 5, and the second has 9 equal sectors numbered from 1 to 9. Using a tree diagram or otherwise, find the probability that both spinners stop at odd numbers.
An experiment consists of flipping a coin and rolling a six sided die once, then observing the upper faces of both. Event is when the coin lands tail side up and the die lands with an even number facing up. Event is when the coin lands head side up and the die lands with an odd number facing up. Determine the range of event , which is the occurrence of events and .
