In how many ways two sections of 30 students each can be formed from 60students?

Let there are 4 sections of 25 students each in a coaching class. Now, out of 150 students 100 are to be selected randomly and entrolled in these sections. Then, the probability that the students A and B (both present in 150 students) are selected and placed in the same section, is

Out of two sections A and B, 10 students of section B shift to A, as a result strength of A becomes 3 times the strength of B. But, if 10 students shift over from A to B, both A and B become equal in strength. Ratio of the number of students in section A that of section B is

In a school,there are 1,000 students,out of which 380 are girls.Out of 380 girls,10% of the girls scored highest in GS. What is the probability that a student chosen randomly scored highest in GS given that the chosen student is a girl?What value do you observe in it?

If the average marks of 30 students of section A is 55 and the average marks of 30 students of section B is 60 ,then find the combined average of both the sections.

If the average marks of 30 students of section A is 55 and the average marks of 30 students of section B is 60 ,then find the combined average of both the sections.
