There are two groups each having 10 girls. The two tallest girls can be in the same group or they can be in different groups. So, there are two possibilities for the tallest girls.

∴ Probability that the two tallest girls are in different groups, p = $\frac{1}{2}$

$∴ \frac{19}{2} p = \frac{19}{2} \times \frac{1}{2} = \frac{19}{4}$
