If the digits are in-creasing, then no digit can be 0 and any collection of 5 numbers with repeats from 1 through 9 has one way to arrange them in an increasing order.

      1 Introduction Monte Carlo refers to a broad class of algorithms that solve problems through the use of random numbers. They first emerged in the late 1940’s and 1950’s as electronic computers came into use [1], and the name means just what it sounds like, whimsically referring to the random nature of the gambling at Monte Carlo, Monaco.

Now, let Y = X2 (i.e., we pick a uniformly random number between 1 and 3, and compute its square). In this note, I’m going to work through how we would find the PDF of Y, which we’ll call f Y (y), and how we can use that to ...

      For a dice roll, the random number chosen should be between 0 and 6, so you will need to change the number in the ‘pick random’ block to have a value of 6 instead of 4. Having picked the random number, you will then need to display the number somehow.

One can also include a line of code that sets the initial seed, or have the program pick a ”random” seed. To generate a random number with uniform probability between a and b, the following code should work:
