There is 20 students in mr.millers algebra class. 14 of the students are females. if mr.miller selects a student at random, what is the probability that he will select a male

To solve for the probability that Mr. Millers will select a male in his algebra class, first solve for how many male is there in the class. 
To solve for how many male is there, subtract the total number of students by the total number of female students. Since there are 20 students in the algebra class and 14 are females, subtract 20 by 14 to get the number of male students.
> 20 - 14 = male students
> 6= male students
There are 6 male students in Mr. Miller's algebra class.
To solve for the probability that Mr. Millers will select a male in his algebra class, divide the number of male students by the total students.
> 6/20= the probability that Mr. Millers will select a male in his algebra class
> 3/10= the probability that Mr. Millers will select a male in his algebra class
This means that Mr. Miller will have the probability of 3 in every 10 students that he will select a male student.
