When the farmer’s dog is let loose, it chases either the ducks with probability \(\frac{3}{5}\) or the geese with probability \(\frac{2}{5}\). If the dog chases the ducks there is a probability of \(\frac{1}{10}\) that they will attack the dog. If the dog chases the geese there is a probability of \(\frac{3}{4}\) that they will attack the dog. Given that the dog is not attacked, find the probability that it was chasing the geese.
