Answer:

The number of color are possible
\left n} \atop }} \right. C _r = 1215450

Explanation:

From the question we are told that

The number of colors is r = 4

The sample size n = 75

The number of color that are possible can be mathematically evaluated as


\left n} \atop }} \right. C _r = (n !)/( (n-r)! r!)

substituting values


\left n} \atop }} \right. C _r = (75 !)/( (75-4)! 4!)


\left n} \atop }} \right. C _r = (75 !)/( (71)! 4 !)


\left n} \atop }} \right. C _r = (75 *74 * 73* 72 * 71!)/( (71)! (4*3*2 *1))


\left n} \atop }} \right. C _r = 1215450
