Solution

Flu 1st year - yes

Flu next year probability = 20% no flu next year --- 80%

Flu later year probability = 20% flu later year probability ---30%

So flu after 2 years = 0.04+0.24 = 0.28 =28%

Every year probabilities,

0.8*0.3 So in life time he has flu for 24% of time.

Problem(5)

(-3-4i)^3 = 117-44i

(5-6i) / (3i - 3) = (-11+i)/6

b11 = (-1/10 -i/5)
