There are 100 employee in sales office of a multinational company. Let P(Ei) be the probability that exactly i out of 100 employee are infected with swine flu virus. If P(Ei) is directly proportional to i(i + 2); 1 ≤ i ≤ 100. If the probability that a person selected at random is found to be positive for this virus is given by 108p/575, then p is equal to _____.
