ans:
all=red+blue= 6+2/3=6+4/6
blue= 5/6
red=6+4/6-5/6=5+5/6
red/all=5+5/6 / 6+4/6 = 35/6 / 40/6 = 35 /40 = 7/8
blue/al= 5/6 / 6+4/6 = 5/6 / 40/6 = 1/8 (1- 7/8 =1/8 )
all=red+blue= 6+2/3=6+4/6
blue= 5/6
red=6+4/6-5/6=5+5/6
red/all=5+5/6 / 6+4/6 = 35/6 / 40/6 = 35 /40 = 7/8
blue/al= 5/6 / 6+4/6 = 5/6 / 40/6 = 1/8 (1- 7/8 =1/8 )
