When Ms Shreve randomly selects a student in her class, she has 1/3 probability of selecting a boy.
A: If her class has 36 students, how many boys are in her class?
B: if there are 11 boys in her class, how many girls are in her class?
C: what is the probability that she will select a girl??
I have a general idea on this but I don't know if it's right.
