In your own words, write the meaning of each vocabulary term. probability experiment: an action/trial that has varying results outcome: the results... what you get event: is a collection of one or more outcomes sample space: the set of all possible outcomes probability of an event: P(event) = in decimal form is the likelyhood/chance that the event will occur P(event) = P(heads) Exercise 1: In Exercises 1 and 2, find the number of possible outcomes in the sample space. Then list the possible outcomes. A stack of cards contains the thirteen clubs from a standard deck of cards. You pick a card from the stack and flip 1 two coins.

Find the probability that (a) the sum of the two numbers is not 10 P(not 10) 1 - 9/100 = 91/100 = 0.91 look for = 10 1 + 9 2 + 8 3 + 7 4 + 6 5 + 5 6 + 4 7 + 3 8 + 2 9 + 1 = total of 9 1 - 9/100 = 91/100 = 0.91 and (b) the product of the numbers is greater than 10. P(less than 10) = 27/100 27/100 = 23/100 = 0.23 1 * 1 = 1 2 * 1 = 2 3 * 1 = 3 4 * 1 = 4 5 * 1 = 5 6 * 1 = 6 7 * 1 = 7 8 * 1 = 8 9 * 1 = 9 10 * 1 = 10 1 possible 2 possible 3 possible 4 possible 5 possible 6 possible 7 possible 8 possible 9 possible 10 possible Question 4: At a school dance, the parents sell pizza slices. The table shows the number of pizza slices that are available. A student chooses a slice at random. What is the probability that the student chooses a thin crust slice with pepperoni? Pepperoni | Plain Cheese Thin Crust | 34 | 36 Thick Crust | 8 | 12 Event = 34 Total = 34 + 36 + 8 + 12 = 90 34/90 = 0.37
