Hey folks,
I’m slightly behind on posting here – sorry! You should be finished Probability Practice 3 by now, and starting into Probability Review 1. The Skills Tracking Booklet is printed on pink paper this time, by special request. :)

We finished Probability Practice 2, and I handed out a take-home quiz. Try not to use your notes, and if you have to use them please note that at the top of your page. You’ll hand your quiz in at the start of class tomorrow.
We’re going to start Probability Practice 3 tomorrow:
Mutually exclusive and Non-mutually exclusive events. Phew.
Here’s the work for this evening. Remember, you’re spending at least 30 minutes on this tonight: 07 – Probability Practice 2
A compound event is comprised of a sequence of two or more single events. Those single events are independent if the probabilities of later events are not affected by whether earlier events occurred. If they are affected, the events are dependent.
For example, when flipping a coin then rolling a die, the probability of rolling a 5 or 6 does not depend on the outcome of the coin flip. These events are independent.
When drawing two cards in a row from a shuffled deck of cards, the probability of drawing a 5 as the second card depends on the outcome of the first card drawn. If the first card is a 5, there is a reduced probability of drawing a 5 as the second card. These events are dependent.
Here’s your homework. We kind of did question 1 already in class, so you can skip it if you like.
We have a mini-lesson about using combinatorics to calculate the probability of events when all outcomes are equally likely. We worked on these questions:
02 – Probability with Equally Likely Outcomes
And tomorrow you’ll work on Probability Practice #1:
Here’s what we started today:
Hey everyone,
Here’s a bunch o’ stuff that we’ve been working on, including some solutions. There are quiz solutions on the bulletin board in the classroom as well.
We had a quiz today: 07 – Permutations Quiz
We also started to learn about combinations. Here’s a video that might help if you were having trouble following or if you were away:
Here’s a quick note about factorials, and a longer one about permutations. There is probably a couple of days’ worth of stuff here. We’ll see.
