conversations.value: 5 out of 19 marbles are yellow so the remainder which is 19-5 = 14 marbles are blue and red
  14 marbles are split into blue and red in the ratio 3:4 so each "share" is 14/(3+4) = 2 marbles
  There are 4 "shares" of red marbles which totals to 4*2 = 8 red marbles
  There are 8-5 = 3 more red marbles than yellow marbles
