Find the attached solution....I am here for any edits/revision

1. There are 60 customers, that may come to supermarket.
a. Considering the binomial probability distribution
Probability of success is 𝑝 = 0.2
Probability of failure is 𝑞 = 1 − 𝑝 = 1 − 0.2 = 0.8
Probability of having exactly one customer in a time...
