From the list of telephone numbers of $100$ employees of a factory, the following frequency distribution of their unit place digit (for example, in the number $25828573$, the unit place digit is $3$) is given in the table below:
Unit digit $0$ $1$ $2$ $3$ $4$ $5$ $6$ $7$ $8$ $9$ Frequency $8$ $9$ $12$ $15$ $10$ $7$ $12$ $10$ $9$ $8$
Find the probability that a randomly selected employee has a telephone number with unit digit $3$.
| Unit digit | $0$ | $1$ | $2$ | $3$ | $4$ | $5$ | $6$ | $7$ | $8$ | $9$ |
| Frequency | $8$ | $9$ | $12$ | $15$ | $10$ | $7$ | $12$ | $10$ | $9$ | $8$ |
Find the probability that a randomly selected employee has a telephone number with unit digit $3$.
