Question 1205980
<font color=black size=3>
P(boy) = probability of a boy
P(girl) = probability of a girl


P(boy) = (number of boys)/(number of students)
P(girl) = (number of girls)/(number of students)


Example:
A very small school has 10 boys and 12 girls
P(boy) = 10/(10+12) = 10/22 = 5/11
P(girl) = 12/(10+12) = 12/22 = 6/11
These results aren't the final answers to your particular problem; however, you can use this example to answer your question.
