Total number of possible outcomes = 100

Number of favourable outcomes (Getting a square number) = 10 (1, 4, 9, 16, 25, 49, 64, 81, 100)

P(Getting a square number) = $\dfrac{\text{Number of favourable outcomes}}{\text{Total number of possible outcomes}}$

= $\dfrac{10}{100}$

= $\dfrac{1}{10}$

Hence, the probability of getting a square number is $\dfrac{1}{10}$ .
