Hi.

Can the required density be understood as a piecewise
linear function going through 4 or 5 given points?

I did not succeed to reconstruct the sequence of points,
through which the density curve should go.

The first point seems to be (0, 0.2).
Is 0.23 x-coordinate or y-coordinate?
The point (0.21, 0.3) has lower x-coordinate than
the point 0.25 on X-axis.

The density function should have the definite integral
equal to 1. Is this true?
