1. Warm-up: Read problem 36 below and answer the questions that follow.
a) Make a conjecture. What do you think the probability of having two or three girls in a family of three is?
b) Design a computer simulation that would help you solve this problem.
2. Finish Lesson 5.2.2 (page 260)
Janelle’s aunt and uncle have three children, two of whom are girls. Assuming that girl children and boy children are equally likely, Janelle thought that the chance of having two or more girls out of 3 children must be 50%. Janelle’s brother thought the chance of having so many girls had to be less than 50%.

2. Finish Lesson 5.2.2 (page 260)
- Complete Problems 36 and 37 in teams
- 20 minute timer--if you don't finish, it's homework
3. Start Lesson 5.2.3 Compound Independent Events (page 263)
- Objectives
- I will determine whether an event is dependent or independent
- I will calculate the probability of compound independent events
- Problem 43 in teams. Stoplight. Check with Mr. Robinett before moving on
- Problem 44 and 45 in teams. Stoplight. Check with Mr. Robinett before moving on
Closure: Summarize your understanding of independent and dependent events. How can you determine if two events are independent of one another?
