A survey found that 48% of bank customers preferred mobile banking as the method to manage bank accounts.

If 7 bank customers are randomly selected, find the probability that at most one bank customer preferred mobile banking as the method to manage bank accounts. Round answer to three significant digits.

Hint :
P(x)=(n)pˣ(1-p)ⁿ⁻ˣ
(x)

Remember At most means ≤ so
P(x≤ k)=P(0)+P(1)+...P(k)
