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} ).
A committee of 4 boys and 3 girls is chosen from 8 boys and 5 girls One of the boys is a brother of one of the girls Probability that both are in the committee is?
4/8 x 3/5
What is the probability that a teacher will pick a boy out of 21 students 9 girls and 12 boys?
12/21 or 4/7

There are 4 boys and 3 girls What is the probability the boys and girls sit alternately?
1/35
What is the probability a girl is chosen if 15 students are girls and 10 students are boys?
The ratio of girls to total students is 15:25, or 3:5. Three out of five students are girls so there would be a 60% probability that a girl would be chosen; a 2 out of 5 chance, or 40% probability that a boy would be chosen.
What if a class of 25 students has 15 girls and boys if one student is chosen at random what is the probability it is a girl?
The probability is 15/25 = 3/5
A class of 25 students has 15 girls and 10 boys If one student is chosen at random What is the probability it is a girl?
The probability is 15/25 = 3/5
A committee of 4 boys and 3 girls is chosen from 8 boys and 5 girls One of the boys is a brother of one of the girls Probability that both are in the committee is?
4/8 x 3/5
What is the probability of a girl being chosen if there are 10 boys and 14 girls?
If the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.

A school debate team has 4 girls and 6 boys. A total of 4 of the team members will be chosen to participate in the district debate. What is the probability that 2 girls and 2 boys will be selected?
3-7
What is the probability that a teacher will pick a boy out of 21 students 9 girls and 12 boys?
12/21 or 4/7
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
What is the probability you will select a girl from the class if you have 17 girls and 10 boys?
Oh, dude, let me break it down for you. So, if you have 17 girls and 10 boys in the class, the probability of selecting a girl is like the number of girls divided by the total number of students. So, it's 17 girls out of 27 students, which simplifies to about 63%. Cool, right?
