Period B--you're forced to study, because you have tonight's take home quiz to complete. A couple hints...
- In your simulation, it tells you numbers for each coupons; if you use these in your simulation and generate 2 digit numbers, you would just ignore numbers over 50. Make sure you say so in your procedure!
- It also says that coupons are given without replacement--this means that no numbers can repeat--again, make sure your procedure says so!
- Finally, the question does not ask you how many coupons it takes to equal or exceed $300 (this is what most of us initially thought). Instead, it's asking you for the distribution of the number of prize winners. That is, how are these prizes distributed? In other words, how many people (in all of your trials combined) won $50? How many won $100? How many won $200?
- So, if I finish my three trials and awarded 9 total coupons, I want to find the percentages that were each amount. For instance, maybe 5 of the 9 coupons were for $50--that's about 55%. And if 0/9 are $100, that's 0%. The remaining 4 of the 9 awarded were $200, that's about 45%.
Periods E,F: Finish the multiple choice if you did not do so in class. Also, some of you (in period F) needed to finish the "coupon" problem we started in groups. Please do so!
Here are some practice problems for you to try for your quiz (if you like)...
- Suppose all students donate uniform items to EHHS when they graduate. 30% of students will donate 2 items, 50% of students will donate 3 items, and the rest will donate 4 items. Use a simulation to determine how many students will need to donate in order to collect 20 uniform items.
- Why is the simulation incorrect?
- Generate a number to represent hitting a baseball. Let all the odd numbers represent a homerun, and all the evens represent an out.
