MDM4U Probability Practice

I haven’t posted a good lesson summary in a while, but there’s one coming (I promise).

So far we’ve learned some basic probability concepts. In your textbook you’ll find the concepts shown in section 6.1-6.4 (but not 6.2).

Today’s practice work (I’m at the Board Office) is the following; please complete all of it during class. If you can’t finish, spend up to 30 minutes on it for homework. We’ll talk about any challenges you have tomorrow.

MDM4U Permutations Practice

We started working with playing cards today. Your home is this question:

You deal 5 cards from a deck of 52 cards, 1 card to each of 5 people. How many different unique arrangements are there that include all 4 queens?

A solution:

Since all four queens are included, there are only 48 cards left to choose from for the fifth card. There are 5! ways to arrange the five cards, so this means there are (48)(5!) = 5760 total arrangements.
