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} ).

Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the larger class.?
Let the number of students in the smaller class be ( x ). Then, the larger class has ( x + 6 ) students. The total number of students in both classes is given by the equation ( x + (x + 6) = 50 ). Solving for ( x ), we get ( 2x + 6 = 50 ), which simplifies to ( 2x = 44 ), so ( x = 22 ). Therefore, the larger class has ( 22 + 6 = 28 ) students.
What if your teacher was given 130 math books to distribute among his students There are 6 classes that will need books Each class has 21 students How many books will be left after he passes them out?

Mrs. Circle has a class of 30 students. For every three girls in the class there are 2 boys. How many boys are in the class?
To find the number of boys in Mrs. Circle's class, we can set up a ratio based on the information given. For every 3 girls, there are 2 boys, making a total of 5 students in this ratio. If we divide the total number of students (30) by the total parts of the ratio (5), we find that there are 6 groups of this ratio. Since each group has 2 boys, the total number of boys is 6 groups × 2 boys/group = 12 boys.
