Marco tracks the distribution of admissions tickets by age group at his local museum. Using data collected over the past month, he constructs the probability distribution shown below for the age of a randomly selected ticket holder.
Children $0$-$6$ | Youths $7$-$17$ | Adults $18$-$64$ | Seniors $65$+
:-:|:-:|:-:|:-:
$0.25$| $0.35$ | $0.3$ |$0.1$
**What is the probability that a randomly selected ticket holder is over $17$ years old?**
