Answer:

19

Step-by-step explanation:

We have that out of 100 products , 93 are ready for purchase by customers.

The probability of the product being purchased is 93% or 0.93.

The expectation is given by;

E(x)=n*p(x)

If the 20 products are selected, then we have n=20

The expectation is

[tex] \bar x = 0.93 \times 20[/tex]

[tex] \bar x = 18.6[/tex]

Thus approximately 19 customers will be ready to purchase
