In a project there are 9 activites; A, B, C, D which are sequential; E. F, G which are seqential; H, K which are sequential, Also E, F, G run parallel to B, C, D; and H. K run parallel to A, B. C. D. Besodes these activity dependencies, it is also needful that B be completed before taking up G; A and H be completed before taking up D and K. How many dummies are to be drawn on the activity network?
