Every day, the number of network blackouts has a distribution (probability mass function)
x | 0 | 1 | 2
p(x)| 0.7| 0.2| 0.1
a small internet trading company estimates that each network blackout results in a $500
loss. compute expectation and variance of this company’s daily loss due to blackouts.
i computed this e(x)= .4 , varx= .44, but i don't know how i can find the answer?
the answer is
e(y ) = 200 dollars,
var(y ) = 110, 000 squared dollars.
