136. In the first jar there are 3 blue marbles and 6 red marbles, and in the second jar there are 4 blue marbles and 5 red marbles. Two coins are tossed. If the total number of heads is more than 9, one marble is taken from the first jar and added to the second jar. Otherwise, one marble is taken from the second jar and added to the first jar. Now one marble is selected from the jar with more marbles. What is the probability that this marble is red? (1) $\dfrac{157}{270}$ (2) $\dfrac{165}{270}$ (3) $\dfrac{173}{270}$ (4) $\dfrac{185}{270}$
