Find the area of the shaded region below. What fraction of the entire figure does the shaded portion make up? 9 cm Compute the following expressions with fractions = 1 – 12 = * 3 = 4 ÷ 1 = Bell work
Section 7-2: Theoretical and Experimental Probability
Instructions Everyone needs three vocabulary sheets. You will each have assigned vocabulary terms. Group 1—Probability and Outcome Group 2—Sample Space and Event Group 3—Equally Likely Outcomes and Favorable Outcomes Group 4—Theoretical Probability and Complement Group 5—Geometrical Probability
Theoretical Probability A CD has 5 rock songs and 8 R&B songs. What is the probability that a randomly played song will be a rock song? An R&B song? A country song?
Theoretical Probability We are playing the game Battleship. There are 100 holes on each game board and each player has 5 ships to place. One ship takes 2 holes, two ships have 3 holes, one has 4 holes, and the final ship has 5 holes. What is the total number of holes that would result in a hit? What is the probability that your opponent will miss?
Probability with Permutations and Combinations Every student receives a 4 digit code for the library computers and no numbers repeat. Mary has the code Is this a permutation or combination? What is the probability that a code will be made up of consecutive numbers?
Geometrical Probability From the warm-up: What fraction of the entire figure was represented by the shaded triangle? What is the probability that a randomly chosen point would lie in the shaded triangle?
Guided Practice A red die and a blue die are rolled. If all numbers are equally likely, what is the probability that the sum will be 9? What is the probability that a (402) phone number will end in 00? (Assume that all phone numbers are equally likely.) Find the ratio of the shaded area to the entire area. What is the probability that a random point is not in the shaded area? 5 in. 10 in.
