Answer: The ration for 27:71, would be 3/8. Hope this helps!
R/B = 1/4
<span>R = 4B </span>
<span>For every red, there are 4 blues </span>
<span>Let there be x reds and 4x blues (5x counters in all) </span>
<span>P(red,red) = (x/5x)((x-1)/(5x-1)) = 6/155 </span>
<span>(155)x(x-1) = (6)5x(5x-1) </span>
<span>155x^2-155x = 150x^2-30x </span>
<span>5x^2-125x = 0 </span>
<span>5x=125 </span>
<span>x= 25 reds
