4.1-4.3 Expected Value and Binomial Distribution

Comic of the Day

Tip: Some components of group assignments should be done together, then assign individuals to finalize separate parts later.  Allow time to discuss/evaluate each group members contributions and make changes if necessary.

Warmup

1. Which of the two probabilities below would be easier to calculate? (Hint: Think if AND or OR would be required)
a) What is the probability that at least two people in our class of 30 students share a birthday? 
b) What is the probability that there are no shared birthdays?

2. What do we call the relationship between these probabilities?

3. Solve using Excel

Deadlines

Today - 4.1-4.3 Expected Value and Binomial Distribution

Plinko

a) If the token is always dropped in the middle, do all of the outcomes (prize values) have an equal likelihood?

b) What would happen if the Plinko board wasn't perfectly level (i.e. it was tilted slightly sideways)?

Simulator - Set rows = 26 and binary probability p = 0.10 to simulate a company with 26 employees and an injury rate of 10.0 (%).  How many injuries are possible?  How many injuries are expected?
