This is Mathematica project. Just need few codes, but I cant figure out. Help me

Setup a random walk experiment where the step size is a "Normal Distribution". randomwalk = Join [{0}, Accumulate [Randomvariate ["your distribution goes here", steps]]]; (* set up an array of accumulated random steps *) steparray = Range [O, steps]; (* set up the step array for plotting *) ListLinePlot [Transpose [{steparray, randomwalk}], PlotRange rightarrow {All, {-20, 20 read about the Transpose command *) Setup a random walk experiment where the step size is a "Normal Distribution". randomwalk = Join [{0}, Accumulate [Randomvariate ["your distribution goes here", steps]]]; (* set up an array of accumulated random steps *) steparray = Range [O, steps]; (* set up the step array for plotting *) ListLinePlot [Transpose [{steparray, randomwalk}], PlotRange rightarrow {All, {-20, 20 read about the Transpose command *)
