3 Unit Thursday 12 March

Hey Guys,

3 unit will be on in the morning – I may be about 10 minutes late as I can only drop of my kids to childcare from 7:30.  We are going to discuss some introductory concepts about polynomials – go to room 19 first  -but I may be in room 22 with the projector to demo some stuff

Cheers

Mr B

Remember:

Arranging – use a permutation (order is important in arrangements)
Choosing – use a combination (the order doesn’t matter, just whether something was chosen.

AND – multiply
OR – add – mutually exclusive
