To find the probability that a girl will be chosen as president, you can use the formula for probability: ( P(\text{girl}) = \frac{\text{number of girls}}{\text{total number of students}} ). There are 9 girls and 12 boys, making a total of 21 students. Thus, the probability is ( P(\text{girl}) = \frac{9}{21} = \frac{3}{7} ).

A nursing class has 13 women and 18 men if a student chosen randomly to be the team leader what is the probability the student is a woman?

least likely


In a second grade class containing 13 girls and 9 boys 2 students are selected at random to give out the math papers. What is the probability that the second student chosen is a boy given that the fir?

To find the probability that the second student chosen is a boy given that the first student chosen is a boy, we first note that there are 22 students total (13 girls and 9 boys). If the first student chosen is a boy, there will then be 8 boys and 13 girls remaining, making a total of 21 students left. Therefore, the probability that the second student is a boy is the number of remaining boys (8) divided by the total remaining students (21), which gives us a probability of ( \frac{8}{21} ).

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%.


How many ways can a president vice president and secretary be chosen for a committee of 9 people?

How many ways a president vice president and secretary be chosen from a committee of 8?

To choose a president, vice president, and secretary from a committee of 8 members, we can select the president in 8 ways. After selecting the president, 7 members remain for the vice president, and after that, 6 members are left for the secretary. Thus, the total number of ways to choose these three positions is (8 \times 7 \times 6 = 336).
