Probability mass and density functions

From the lectures you may recall the concepts of probability mass and density functions. Probability mass functions relate to the probability distributions discrete variables, while probability density functions relate to probability distributions of continuous variables. Suppose we have the following probability density function:

  • Using the barplot function, make a probability histrogram of the above above probability mass function. Specify the height of the bars with the y variable and the names of the bars (names.arg), that is, the labels on the x axis, with the x variable in your dataframe.
