AAnsarii d parameters 4 variance budget wud b d d numbers aftr subtraction na n den v hv 2 identify if its adverse or favorable? ?
u noe na hw 2 wrk dat out..multiply d returns wid d chances of dat occurring.
i. node 1.
success: return= $3m, chances = 0.5. so 3 x 0.5 = $1.5m
failure: return=$0, chances 0.5. 0 multiplied so = 0
success - failure = 1.5 - 0 = $1.5m [returns dat u will gt 4m d promo]
nw subtract d expenditure 4 promo 4m d returns dat u'l gt. 1.5 - 1 = $0.5m.
ii. node 2.
success: return=$4.5 + 0.5m (coz u'll gt dis 4m promoting it later), chances = 0.8. so 5 x 0.8 = $4m
failure: return = ($2m), chances = 0.2. so (2) x 0.2 = ($0.4m)
success - failure = 4 - 0.4 = $3.6m
iii. node 3.
returns - initial investment = 3.6 - 2 = $1.6m
samjha?
all d bestMay Allah Help us get the best in this world n d BEST in d next..!
there is 0 promotion cost!!!!
and it shud be 4.5*0.8 = 3.6 and 0.2*2 = 0.4 then 3.6-0.4 = 3.2 then 3.2-2m = 1.2 .
why will it be 4.5+0.5??
at node 1, u hv further promo or no promo. further has (1), no promo has 0, ofc.
no, even in s10_31 tr told us dat v 1st add d returns, den multiply it wid d probability.
