A statistics course has seven male and three female students. The professor wants to select two students at random to help her conduct a research project. What is the probability that the two students chosen are female?
Heights of the students in a class are given in the distribution below:
5' - 5'2" 10
5'2" - 5'4" 40
5'4" - 5'6" 25 .
