Tories bookcase holds one algebra book one geometry book and 12 books about advanced engineering mathematics. Books are taken at random from her book case, one after another without replacement until an engineer book is had, at which no more books are taken. The random variable Z represents the total number of books taken during this experiment.

The rate of change of the volume of a snowball that is melting is proportional to the surface area of the snowball. Suppose the snowball is perfectly spherical. Then the volume (in centimeters cubed) of a ball of radius r centimeters is
\(\displaystyle\frac{{4}}{{3}}\pi{r}^{{3}}\)
. The surface area is
\(\displaystyle{4}\pi{r}^{{2}}\)
.Set up the differential equation for how r is changing. Then, suppose that at time t = 0 minutes, the radius is 10 centimeters. After 5 minutes, the radius is 8 centimeters. At what time t will the snowball be completely melted.
