B. Due to a global financial shock occurring at a random exponential time S with parameter S > 0, independent of Ti and T2, the issuers now default at the random times min (S, Ti) and min(S, T2). Based on that information, compute: 5) P(min(S, Ti) > t) = 6) P(min( S, T2) t and min(S, T2) > t) = 10) P(None of them defaults before time t) =
