In a class of 60 students. if 25 students play cricket, 20 students play tennis and 10 students play both the games. find the number of students who play neither

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
