x 0 1 2 3 4

P(X=x) 0.8 0.1 0.05 0.03 0.02

X is the amount of faulty products produced in a day.

I am being asked to find the probability of a exactly one product being foulty in a 5 day periode.

I am a bit confused. I know from the table that the probability of exactly one faulty product in 1 day is 0.1.

But for 5 days, is it that ease just to multiply 0.1 by 5? Or is it 0,1^5?
