Answer:

0.6535

Step-by-step explanation:

Given that during a one-hour period twenty-five customers buy gasoline at this station.

Let X be the no of persons out of these 25 who pay by cash.

X has two outcomes and each trial is independent of other.

Hence X is binomial (n=25, p=0.40)

Required probability

= $P(X\geq 10)\\=P(10)+P(11)+...+P(25)\\=\Sigma_{10}^{25} 25Cr (0.4)^r (1-0.4)^{25-r}$

=0.6535
