With conditional probability, you could formulate it this way: P(2 balls of the same color) = P(2 balls are white OR 2 balls are red) = P(2 balls are white) + P (2 balls are red) [since the two conditions are mutually exclusive]
WebHypophosphoric Acid (H4P2O6) Hypophosphoric acid is prepared by hydrolysis and oxidation of red phosphorus by NaOCl, or white phosphorus by water and air. 2 P + 4 NaClO2 + 2 H2O → H4P2O6 + 2 NaCl. There are no P-H bonds and so this acid is not a reducing agent. It has four acidic hydrogens. It contains P-P bond.
