Initially, how many black chips are in a box containing only red chips and black chips, all identical except for color?

1) Initially, the ratio of red chips to black chips in the box is \(3/25\)

2) If \(12\) red chips and \(80\) black chips are removed from the box, the probability of randomly drawing a red chip from the box is \(1/11\)
