A restaurant has an electronic system that randomly selects customers when they pay for their meal to receive a coupon for their next visit. Each customer has a 10% probability of being selected to receive a coupon, and one
customer being selected or not doesn't affect whether or not another customer will be selected.
Suppose that 2 Eustomers pay for their meals, one after the other.
What is the probability that NEITHER customer is selected to receive a coupon?
Round your answer to two decimal places.
