You have two electrical components of two different kinds. The lifetime of the first kind is exponentially distributed with parameter .2 and the lifetime of the second kind is exponentially distributed with parameter .3. If the lifetimes of the two are independent, what is the probability that the first will fail before the second?

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?
