Probability of an Event

Fun with Random Number Generators! (Investigation 1)

During Lab 1 and Investigation 1students learned about Theoretical Probability and Experimental Probability.
Experimental probability measures how likely an event will occur based on repeated trials. 
Experimental Probability = (number of times an event occurs) divided by (number of trials)

In the tech lab, students found Random number generators and were able to set minimum and maximums (lower and upper limits).
Our favorite sites were

• random.org
• mathgoodies.com

Students also learned how to generate random numbers using Excel.
They discovered the formula

• =RANDBETWEEN(1,12)
• displayed Whole Numbers by using the "Decrease Decimal" tool
• learned to propagate the formula from cell A1 to cell A50 by using the Fill Handle (cell's lower right corner)

btw How did you solve problem h page 55? Excel or website random number generator? And, what happens when you perform more simulations?  Were you that curious?

Coordinate Plane

Fun with Number 12! (Investigation 1)

Here's my "Dot-to-Dot."  Don't forget to "lift your pencil" between shapes. (And, don't forget to label your x-axis and y-axis.)

btw - My Dot-to-Dot drawing is in which quadrants? (ec)

Draw my shape, using the (x,y) coordinates below. 

• Draw starting in quadrant II at (-4,5), (-6,5), (-6,0), (-4,0), (-4,1), (-5,1),  (-5,4), (-4,4), (-4,5)
• Lift pencil 
• Draw starting at (-2,4), (-3,4), (-3,-1), (-1,-1), (-1,0), (-2,0), (-2,4)
• Lift pencil
• Draw starting at (2,5), (0,5), (0,2), (1,2), (1,1), (0,1), (0,0), (2,0), (2,3), (1,3), (1,4), (2,4), (2,5)

What color would this shape be if the drawing were shaded hex value #191970? What is the corresponding RGB value and what does RGB mean?
