The base of a solid in the region bounded by the graphs of y=e^-xy=0, and x=0, and x=1. cross sections of the solid perpendicular to the x-axis are semicircles. what is the volume, in cubic units, of the solid?

The diameter of each semicircular cross-section is given by the vertical distance between the curves and , which is just .

Given a semicircle with diameter , its area is , so the area of each semicircular section is .

The volume of the solid is obtained by integrating from 0 to 1:

step-by-step explanation:

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
