• Mac Chrome users annoyed with swipe gestures moving you “back” from RStudio Server, there is a fix to disable it. If you need help, let me know.


  • Slides: History of probability, two approaches to studying probability, the Powerball lottery analogy, the mosaic package for random simulations.
  • In-class exercise: Go over the code below, then do the following learning checks:
    • LC1: Create a histogram of the number illustrating the long-run behavior of flipping a coin 10 times.
      • Where is it centered?
      • Describe the shape of the distribution of values
    • LC2: Tie all elements of Line 13 of code below to the Attributes of Powerball seen in the slides above.
    • LC3: Try to replicate the above, but for the sum of two die rolls. Hint: resample(c(1:6), 2)
