#51/145 or 0.3517 or 35.2%#

Find the number of boys and girls in the class:

boys : girls# = 2 : 3#

There are #12# boys, so there are #18# girls.

The total in the class is #30#

#P("Girl") = 18/30#

Once a girl has been chosen, there are now #17# girls left out of #29#

#P(G,G) = 18/30 xx17/29#

#=51/145#

This can also be given as #0.3517 or 35.2%#
