各位数学系的高手 抱歉很冒昧来打扰 只是走投无路就想到母校 这这样的 我在国外读书 有一题期末考题真的不会 想请高手给一点指示 对不起 Let {X(t)|t>=0} and {X(t)|t>=0} be independent homogeneous Poisson processes with intensity parameters namda>0 and miu>0 respectively. a) Let M(t) = min{X(t),Y(t)}. Is {M(t) | t>=0} a Poisson Process? Why or why not? If it is, what's the intensity parameter? b) Let N(t) = max{X(t),Y(t)}. Is {N(t) | t>=0} a Poisson Process? Why or why not? If it is, what's the intensity parameter? 谢谢 --
