Answer:
total number of sticks=x+3+x+7=2x+10
probability of paper stick=(x+3)/(2x+10)
probability of wooden stick=(x+7)/(2x+10)
It is given
(x+3)/(2x+10) + (x+7)/(2x+10)=32/100
This is not possible. Another possibility is
(x+3)/(x+7)=0.32
x+3=0.32(x+7)
x(1-0.32)=0.32×7-3
x0.68= 2.24-3=a negative number not possible
