Step 1	\(E[min(T,t)] = t – 0,005{t^2}\) \(E[min(T,40)] = 40 – 0,005{(40)^2}\) \(E[min(T,40)] = 32\) \(E[min(T,t)] = \int_0^t {{}_x{p_0}dx} \) \(E[min(T,40)] = \int_0^{40} {{}_x{p_0}dx} \) \(\int_0^{40} {{}_x{p_0}dx} = 32\)
Step 2	\(E[T] = \int_0^{40} {{}_x{p_0}dx} + \int_{40}^\omega {{}_x{p_0}dx} \) \(62 = 32 + \int_{40}^\omega {{}_x{p_0}dx} \) \(\int_{40}^\omega {{}_x{p_0}dx} = 30\)
Step 3	\({\mathop e\limits^o _{40}} = \frac{{\int_{40}^\omega {{}_x{p_0}dx} }}{{{}_{40}{p_0}}}\) \({\mathop e\limits^o _{40}} = \frac{{30}}{{0,6}}\) \({\mathop e\limits^o _{40}} = 50\)
