Five chips numbered 1 through 5 are placed in a bag. a chip is drawn and replaced. then a second chip is drawn. find the probability that one chip is even and the other is odd. (hint: you can choose an even chip and then an odd chip, or an odd chip and then an even chip.)

There are 3 odd and 2 even numbers involved here.

So Prob( even then odd) = 2/5 * 3/5 = 6/25

Pro(odd then even) = 3/5 * 2/5 = 6/25

Therefore  Prob( either of the above) = 6/25 + 6/25 = 12/25 (answer)

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.
