A bag has 13 red, 14 green and 15 black balls. The probability of getting exactly 2 blacks on pulling out 4 balls is P1. Now the number of each colour ball is doubled and 8 balls are pulled out.The probability of getting exactly 4 blacks is P2. Then

#Section 1: Engineering Mathematics
  1. P1 = P2 
  2. P1 > P2
  3. P1 < P2
  4. none of these
