3. Set Notation How do we write in set notation? {a,b,c,….} Empty = {ø} Set A = {1,2,3,4,5,6,7,8} Set B = {3,4,5,6} What is A union B? What is A intersect B? What is B’?

4. Conditional Probability

5. Conditional Probability contains a condition that may limit the sample space for an event. You can write a conditional probability using the notation - This reads “the probability of event B, given event A”

6. The table shows the results of a class survey. Find P (own a pet | female) The condition female limits the sample space to 14 possible outcomes. Of the 14 females, 8 own a pet. Therefore, P(own a pet | female) equals. 8 14 Do you own a pet?YesNo Female86 Male57

7. The table shows the results of a class survey. Find P (wash the dishes | male) The condition male limits the sample space to 15 possible outcomes. Of the 15 males, 7 did the dishes. Therefore, P(wash the dishes | male) 7 15 Did you wash the dishes last night? YesNo Female76 Male78

8. Using the data in the table, find the probability that a sample of not recycled waste was plastic. P (plastic | non-recycled) The probability that the non-recycled waste was plastic is about 13%. = 20.4 156.3 0.13 P(plastic | non-recycled) = 20.4 48.9 + 10.1 + 9.1 + 20.4 + 67.8 MaterialRecycledNot Recycled Paper34.948.9 Metal6.510.1 Glass2.99.1 Plastic1.120.4 Other15.367.8
