Total possibilities of any 4 from 22 is (22 x 21 x 20 x 19)/(4 x 3 x 2) ie 7315.
Any 2 boys out of 8 is (8 x 7)/2 ie 28 and any 2 girls out of 14 is (14 x 13)/2 ie 91.
These pairs can be combined in 91 x 28 ways ie 2548 so probability of 2 & 2 is
2548 out of 7315 which is 0.35 all but a whisker!

In a classroom the students are 11 boys and 1 girl if one student is selected at random find the probability that the student is a girl?
There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
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} ).
What is the probability of picking a student out of 800 students 50 faculty members and 150 adminstrators?
Probability of picking a student is 800 / (800+50+150) = 800 / 1000 = .8.
What is the probability that a student does not make honor roll if 3 out of 5 students make honor roll?

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%.
What is the probability for a student in a dormitory to be selected if 10 percent of the students live in dormitories and a random sample of 100 is selected?
The probability is 10 percent.
In a classroom the students are 11 boys and 1 girl if one student is selected at random find the probability that the student is a girl?
There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
In a classroom the students are 11 boys and 1 girls If one student is selected at random find the probability that the student is a girl?
1/12 =0.08333... ≈ 8.3%
What is the probability that two students will think of the same letter of the alphabet at the same time?
I think it depends on how many students are thinking of alphabet letters at the same time :) The first student will think of a letter from the English alphabet. Then, the second student will think of a letter. The probability that the second student will select what the first student selected is 1/26.
You randomly select 500 students and observe that 85 of them smoke Estimate the probability that a randomly selected student smokes?
85/500 = 17%
There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
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} ).
At a particular school with 200 male students a play football b play basketball and c play both what is the probability that a randomly selected male student plays neither sport?

If 3 out of 8 students are wearing blue shirts the probability that a student is wearing a blue shirt is?
3 students.
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.
In a third grade class containing 12 girls and 10 boys Two students are selected randomly to give out papers What is the probability that the second student chosen is a boy if the first was a girl?
4 in 7 chance
What is the probability of picking a student out of 800 students 50 faculty members and 150 adminstrators?
Probability of picking a student is 800 / (800+50+150) = 800 / 1000 = .8.
