Question

Four boys and three girls enter a competition which relies only on ‘chance’. What is
the probability that a girl wins first prize?

Answer 1

total favorable outcomes/total possible outcomes
=>3/7

Answer 2

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
