WebYes this is correct. 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] WebViolet phosphorus is a form of phosphorus that can be produced by day-long annealing of red phosphorus above 550 °C. In 1865, Hittorf discovered that when phosphorus was recrystallised from molten lead, a red/purple form is obtained. Therefore, this form is sometimes known as "Hittorf's phosphorus" (or violet or α-metallic phosphorus). [17]
