Work out the value of the house when Lisa bought it.

£?

the value of the house when Lisa bought it is 12 £

the value of the house when Lisa bought it is x (x > 0)(£)

because the value of the house increased 1.5% each year for 2 years

=> at the end of 2 years, the value of the house is

[(100 + 1.5)x]*(100 + 1.5) = 10302.25x

=> 10302.25x = 123 627

=> x = 12

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
