A pot contains 5 red and 2 green balls. At random
\( \mathrm{P} \) a ball is drawn from this pot. If a drawn ball is green

W then put a red ball in the pot and if a drawn bail is red, then put a green ball in the pot, while drawn ball is not replaced in the pot. Now we draw another ball randomly, the probability of second ball to be red is
(1) \( \frac{27}{49} \)
(2) \( \frac{26}{49} \)
(3) \( \frac{21}{49} \)
(4) \( \frac{32}{49} \)
