MATH 1711: WEEK 4

Topics for this week are:

• Assigning and Calculating Probabilities
• Conditional Probability, Independence

Objectives for this week:

• Assign probabilities to each outcome of a given sample space
• Learn the basic rules for the probability of an outcome/event
• Find the probability of an event using counting techniques (when all outcomes are equally likely)
• Learn the definitions of conditional probability and independence

Text coverage:     Sections 6.3 - 6.5 of Goldstein, Schneider and Siegel.

Online resources:

• Week 4 Formula Sheet
• Week 4 Practice Problems
• Online notes
  • Notes and examples on assigning probabilities and the properties of probability.We look at various sample spaces and determine the probability of each outcome in the sample space. These examples also illustrate the difference between sample spaces containing "equally likely" outcomes and biased sample spaces.
  • The Georgia Lottery as an application of probability using counting. If you ever wondered what the real chances were of winning the Georgia lottery, now is your chance to find out! Use the basic principle of probability using counting: to find the probability of winning, we calculate the number of winning tickets and divide by the total number of possible lottery tickets.
