In a classroom the students are 12 boys and 6 girls If one student is selected at random find the probability that the student is a girl?
If there are 12 boys and 6 girls, the total number of students would be 18. You are looking for the probability of selecting a girl from the class: 6/18 Just reduce the fraction to its lowest form 6/18 = 2/6 = 1/3 Your answer would be 1/3.

A nursing class has 13 women and 18 men If a student is chosen randomly to be the team leader what is the probability the student is a woman?
The probability that a randomly chosen student is a woman can be calculated by dividing the number of women by the total number of students in the class. In this case, there are 13 women and 31 total students, so the probability is 13/31, which simplifies to approximately 0.419 or 41.9%.
