Probabilities always refer to an outcome, e.g. the probability of being rich, getting an accident, getting married, etc. As a consequence, "predicted probabilities of the interaction terms" can not exist as interaction terms aren't outcomes. You can get predicted probabilities of outcomes for different groups and use those to get an idea of how the interaction effect works. The command for that is -margins-, see -help margins- and Williams (2012). It is impossible for use to give more concrete advise than this, as you did not specify exactly what estimates you were looking for. Hope this helps, Maarten Richard Williams (2012) "Using the margins command to estimate and interpret adjusted predictions and marginal effects."
