Determine the variance from part a and b
Answer:- Date:-16/4/2021 We know that E[T] LE(TO) E[T] 1 = 11 2 E[T] 2x 21 1 + 3X 38 = 2PET: 3LE|T21 = (1 + 3X - 2 (1 + 4/6 +(*2) Ø + $y2 + (533) *E(T2] = 5(1 + +($2 + (* +(834). ) 1A1-A1-A1A E[T3] + 41 41 (1+ HAHAHA E[T] 1+ 5X 52 Thus (a) Eſtime to go from 0 to 4] = E[To] + E[T1] + E[T2] + E[T3] and (b) E[time to go from 2 to 5] = E[T2] + E[T3] + E[T].
