Today we corrected HW questions on Tree Diagrams and introduced Using Experiments & Relative Frequency to Estimate Probability.

After correcting the HW on Probability and returning the tests on Geometry we looked at Section 10.7 Tree Diagrams.

HW: Ex. 10.7 Q.1-6

Today we started Chapter 10 Probability looking at examples and questions from Sections 10.1 to 10.4. 
Key ideas:

• Listing outcomes
• Fundamental Principal of Counting
• Sample space
• Probability scale
• Probability

HW: Ex. 10.3 Q.9 & 10 and Ex. 10.4 Q.3 & 6

Geometry Test

Looked at Pythagoras Theorem questions
Prepare for mid-term test on Geometry tomorrow.

Corrected HW and Introduced Section 9.5 The Theorem of Pythagoras

HW: Ex. 9.5 Q.1-3

• Corrected HW on angles from Ex. 9.1. 
• Returned tests on quadratics. 
• Looked at video in yesterdays blog. 
• Introduced Section 9.2 Triangles: Scalene, equilateral, isosceles and right angled-triangles. 
• Proved that angles in triangle add to 180 degrees. 
• Proved that the exterior angle is equal to the sum of the two interior opposite angles.
  

HW: Ex. 9.2 Q.1-8

Started Chapter 9 Geometry 1
HW: Questions 3-6 from Ex. 9.1
