In the finals of an Angry Birds tournament, Bob is the number one seed, and he’ll win the championship if he wins one game in the finals. The other two finalists are Fran and Julio, and they each need to win two games to claim the title.
(a) Draw a tree diagram and find the
(b) Assuming that all three players haw an equal likelihood of winning any individual game, find the probability of each outcome in the sample space. (Hint: Use the rule you discovered in 25[c].) Make sure that all of your probabilities add to 1!
(c) Use the results of (b) to find the probability of each contestant winning the championship.

A right regular hexagonal pyramid with the top removed (as shown in Diagram 1) in such a manner that the top base is parallel to the base of the pyramid resulting in what is shown in Diagram 2. A wedge (from the center) is then removed from this solid as shown in Diagram 3. 30 Diogram 1 Diegrom 2. Diagram 3. If the height of the solid in Diagrams 2 and 3 is the height of the original pyramid, the radius of the base of the pyramid is 10 cm and each lateral edge of the solid in Diagram 3 is 12 cm, find the exact volume of the solid in Diagram 3, measured in cubic meters.
