Compound events are those events that have an impact on one another. Rolling a die and spinning a spinner have nothing to do with one another (usually). However, pulling a card from a deck, and then pulling another card without replacing the first, do impact each other. The first card being taken out of the deck is going to alter what the second draw has available. Being able to identify situations that do impact each other, and then determining how that impacts the probability of the events, is the goal of this lesson.
Video:
- As you watch the video, copy down the notes in to the unit packet you received at the beginning of the unit.
- You only need to complete the parts of the notes that I complete in the video
- Any other problems/notes that are skipped in the video can be skipped by you.
- I will have a completed set of notes in a binder if you don’t like the missing/blank areas. You can simply copy down the missing parts, or you can try the problems yourself first and then use the copy in the binder to check your work. Whatever you need.
- Again, you can just leave it blank! The above options are just if it would annoy you to have empty spots on the notes pages!
Practice:
- Practice in DeltaMath ~ 12.3 – Compound Events
Mastery Check:
- You may ask for your mastery check if you have completed:
- All notes for this lesson
- All practice for this lesson
- If both requirements are done, come ask me for the mastery check. You will need a pencil or pen.
- Reminders about mastery checks:
- No phones or computers are allowed. Set your playlist on your earbuds prior to asking for the mastery check (if you want/need)
- Calculators and notes are allowed on some mastery checks, but not all. You will need to check the board for which lessons allow it and which ones don’t.
- Mastery checks can only be completed at the designated table.
- Once done with a mastery check…
- Turn in to your class period’s bin
- Continue on to the next lesson until you find out if your mastery check was correct or if it needs to be revised
- You may also help others if you feel confident/comfortable enough to do so
Need More Practice?
Below you will find three documents. These documents are extra worksheet practice problems if you are struggling with the concept we practiced in this lesson.
- For this first worksheet, a QR code is at the end. It can help you with each problem, showing you step-by-step how to finish the problem.
- For the second and third worksheet, they do not have QR codes available, and you can instead use them to test yourself. The first link is the worksheet, while the following link is the answer key to that worksheet.
