  • Determine the mean by multiplying the profit by probability and summing


  • Declare a function definition
  • Evaluate the function for the value for which the ramp is highest
  • Calculate the derivative of the function and find the gradient of the ramp
  • Understand that since the gradient is a sine function with amplitude 1, it must always be less than or equal to 1
  • Find the area
  • After the Activity

    Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
