Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
<h3>What is the discrete probability distribution?</h3>
Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:
Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:
P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.
0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

Answer:
7x
Step-by-step explanation:
4x ( linear function) + 3x ( linear function) = 7x
3% of $2,700
Multiply 2,700 times 0.03.
(2,700)(0.03) = 81
$81.00 interest is earned on $2,700 a year if it is invested at 3%.
The answer is A. You add the extra 10 feet to however high the bird flew from there
