Q&A - Part 2, Q 2.18 Formula is: U(t) = U + ct - S(t) Why t=3 is not used for ct ? Only c is used, why ?
Don't know if u still need this. The question has given us the relevant parameters for a one year period. The solution has treated the three years as a single period. They have therefore adjusted the poisson parameter from 20 to 60(20*3). Therefore your t becomes 1. Happy studies!
