comment How to calculate the cumulative distribution function of discrete distribution?
For discrete distributions we have the cumulative mass function, rather than the cumulative density function, and it is defined as the sum of the probability mass function of the distribution for all $x < x_0$.

comment Given max force due to friction and change in mass, calculating angle of inclination. Paradox?
Surely what you have found here is the angle at which the object will start to slip due to it's own mass? In which case it makes perfect logical sense for it to be independent of it's mass, whilst increased mass will cause greater frictional force, it will also result in greater gravitational force directed down the slope. These two factors should cancel, giving us a quantity independent of $m$.

comment Formulating a game in an economic setting
@Henry, I think I understand; I formulate the problem in terms of each players payoff (their profit) and then maximize to get $p_{L}$ as a function of $p_{R}$, then using symmetry arguments, $p_{L} = p_{R} = p^{*}$, get $$p^{*} = \frac{100 + c}{3}$$. However, how would I formally write the strategy?

@lulu I believe that they can avoid waste, and will produce exactly the number of shoes that the market will absorb. Or at least the situation doesn't specify otherwise?
