Question
The edge roughness of slit paper products increases as knife blades wear. Only 1% of products slit with new blades have rough edges, 3% of products slit with blades of average sharpness exhibit roughness,
and 5% of products slit with worn blades exhibit roughness. If 25% of the blades in manufacturing are new , 60% are of average sharpness, and 15% are worn , what is the proportion of products that exhibit
edge roughness?
Let R = edge roughness
N = new blades
A = blades with average sharpness
W = worn blades
What are the mathematical notation for the following values:
1% =
3% =
5% =
25% =
60%=
15% =
Express the question in mathematical notation;
The proportion of products that exhibit edge roughness* =
*Express in rational number with 2 decimal places.
