Answer:
Step-by-step explanation:
Let X be the no of vehicles that require warranty service within I year out of vehicles sold (9) yesterday.
Each vehicle is independent of the other to get warranty service
Hence X is binomial with p=8% = 0.08
So P(X=x) =
c)
d) Mean = Mean of binomial = np =
Var (x) = npq =
Std dev = square root of variance = 0.8139
