In a classroom, the students are 12 boys and 6 girls. If one of the students is selected at random, find the probability that the student is a girl
there are 18 students in a class, and only 6 of them are girls. which means: 6/18. you simplify it and get 1/3. and that's your probability
To find the probability that a student selected at random is a girl, we need to divide the number of girls by the total number of students.
The total number of students is the sum of the number of boys and girls, which is 12 boys + 6 girls = 18 students.
Therefore, the probability of selecting a girl is 6 girls / 18 students = 1/3.
So the probability that the student selected at random is a girl is 1/3.
