If I apply to 10 undergraduate schools what're the odds I get into AT LEAST ONE?

GPA needs to be put in context. I did see reference to rising trend and concrete reasons for low GPA in 9th grade, but no reference to where she falls in relation to the rest of her class. Is she in the top 10% or at least top 20%? That would help. Also, unclear how competitive her high school is & whether they routinely have students applying to tippy-top schools. Naviance data might help, too.
