Probability of an even=p(e) = no. of favourable outcomes
                                              total no. of possible outcome
therefore,
                 no. of favourable outcome = girls = 3
                 total no. of possible outcomes = girls + boys =3+4 =7
                = posibility =  3
                                       7
