People arrive with poisson process with Rate 2
(C) P( N(1) = 2 Given N(3) = 6)
For this i Said this was equal to N(2) = 4 and worked it out using formula.
(D) This one is driving me crazy.
P N(1) (Greater than or =) 2 Given N(1) (Greater than or =) 1
Help With D and confirmation on C would be greatly appreciaded. Thanks!
