# SurvivalFunction

 SurvivalFunction gives the survival function for the symbolic distribution dist evaluated at x. SurvivalFunctiongives the multivariate survival function for the symbolic distribution dist evaluated at . SurvivalFunction[dist]gives the survival function as a pure function.
• SurvivalFunction gives the probability that an observed value is greater than x.
