Hi,

thanks for reading,

**A)**For my part, i interpreted the different probabilities the same way CaptainBlack did:

So if 90% of the 1000 employees get the bonus at the end of the first year it means:

(1000 employees)x(90%)x(bonus=1000$)

for the second year, 85% of the 900 employees left from the first year would earn the bonus so:

(85% of the 900 employees left= 0.85x900)x(bonus of the second year=1500$)

and so on for the other years

is my reasoning good? if i'm wrong could you please tell me which part exactely is

thank you

Sue
