<h2>Answer:</h2>

The  probability of first drawing a girls name and then a boys name from the hat is:

                \dfrac{9}{55}

<h2>Step-by-step explanation:</h2>

It is given that:

The names of nine boys and two girls are in a hat.

This means that the total number of names in the hat are: 9+2=11.

Also, the probability of first drawing a girls name and then a boys name from the hat is given by:

Probability of drawing a girl name×Probability of drawing a boy name.

Also, the drawing of names is done without replacement.

Hence, we get probability as:

=\dfrac{2}{11}\times \dfrac{9}{10}\\\\=\dfrac{9}{55}

The probability is:  \dfrac{9}{55}
