Expert Solution

Step 1

here given n = 20

p = probability that car needs warranty repair

q = 1-p = 0.8

here use binomial theorem

x= no of car needs warranty repair

BINOMIAL DISTRIBUTION

Each trial is independent
Finite number of trial
There are two outcomes success and failure
Probability of success remain constant in each trial

$p (x = r) = (\binom{n}{r}) (p)^{r} (q)^{n - r}$
