While loop won't plot while remebering numbers

I'm trying to write a kind of gambling game, in which all the results should be plotted in a graph. I used a While loop and nestled a switch in it, the program works but it won't plot. Would be great to get some help!

You're overwriting b each time though the loop, and not saving values to an array as you go along. So at the time of plotting, both b and n are scalars. And if you plot a single plot point without a marker, nothing will be visible.
