  Probability & Simultaneous Equations Java Applets
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=a__hh_tool__g-1
  Sione writes, "I have just put up two applets .... One applet
  is for Probability calculations, where it does experimental
  simulations, equally likely events, probability tree....The
  second applet is for solving step-by-step of a pair of
  simultaneous equations either by 'substitution' or
  'elimination' methods."
