First, create a $$10,000\backslash$times $100$$ matrix called $**$mymat$**$ using a $`$for$()`$ loop, where the $`$rbinom$(100,1,0\mathrm{.}5)`$ line of code is used $10,000$ times to populate each row of the matrix. $($You are filling in a whole row of the matrix all at once with the above line of code.$)$ Next, using another $`$for$()`$ loop $($or the same $`$for$()`$ loop$),$ create a vector $`$x$`,$ where each component of $`$x$`$ is the mean of the corresponding row of the matrix. Notice that calculating the mean of each row will give you the proportion of $1$s in that row. Then make a histogram of the $`$x$`$ vector. Do not print the matrix or the vector or else you will get very long output in your output pdf file.
