Presentation transcript:

Warm-up Howard is playing a carnival game. The object of the game is to predict the sum you will get by spinning spinner A and then spinner B. List the sample space. What is the probability Howard gets a sum of 5? Suppose that Howard gets a 3 on Spinner A, what is the new probability of him getting a sum of 5? 3/12 or 1/4 1/3

Conditional Probability

Conditional Probability Contains a condition that limits (or restricts) the sample space for an event

Conditional Probability Written as “The probability of event B, given event A”

Conditional Probability Formula

The table shows the results of a class survey, “Do you own a pet?” Find P(own a pet | female). Yes No Female 8 6 Male 5 7

The table shows the results of a class survey, “Did you wash the dishes last night?” Find P(wash the dishes | male) Yes No Female 7 6 Male 8

Using the data in the table, find the probability (as a percent) that a sample of not recycled waste was plastic. P(plastic | non-recycled) Recycled Not Recycled Paper 34.9 48.9 Metal 6.5 10.1 Glass 2.9 9.1 Plastic 1.1 20.4 Other 15.3 67.8
