First, multiply 3.5 by 20 and 2 by 20 to get the real width and length of the room(That would be 70 in. long and 40 in. wide). Then, change that into feet (Which would be 5.8 ft. long and 3.3 ft. wide). Lastly multiply the length by the width. The answer would then be 19.14.

Answer:
Step-by-step explanation:
The variable x, that said the number of customer that will order a nonalcoholic beverage in a sample of n customers follows a binomial distribution. Because we have n identical and independent events with a probability p of success and (1-p) of fail.
So, the probability that x customers will order a nonalcoholic beverage is:
Where n is the size of the sample and p is the probability that a customer order a nonalcoholic beverage, so replacing the values, we get:
Now, the probability that at least 7 will order a nonalcoholic beverage is equal to:
Where:
So, is equal to:
Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886
