Answer:
The probability of getting two consumers comfortable with drones is 0.3424.
Step-by-step explanation:
The probability that a consumer is comfortable having drones deliver their purchases is, <em>p</em> = 0.43.
A random sample of <em>n</em> = 5 consumers are selected, and exactly <em>x</em> = 2 of them are comfortable with the drones.
To compute the probability of getting two consumers comfortable with drones followed by three consumers not comfortable, we will use the Binomial distribution instead of the multiplication rule to find the probability.
This is because in this case we need to compute the number of possible combinations of two consumers who are comfortable with drones.
So, <em>X</em> = number of consumers comfortable with drones, follows a Binomial distribution with parameters <em>n</em> = 5 and <em>p</em> = 0.43.
Compute the probability of getting two consumers comfortable with drones as follows:
![P(X=x)={5\choose x}\ 0.43^{x}\ (1-0.43)^{5-x};\ x=0,1,2,3...](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%7B5%5Cchoose%20x%7D%5C%200.43%5E%7Bx%7D%5C%20%281-0.43%29%5E%7B5-x%7D%3B%5C%20x%3D0%2C1%2C2%2C3...)
![P(X=2)={5\choose 2}\ 0.43^{2}\ (1-0.43)^{5-2}](https://tex.z-dn.net/?f=P%28X%3D2%29%3D%7B5%5Cchoose%202%7D%5C%200.43%5E%7B2%7D%5C%20%281-0.43%29%5E%7B5-2%7D)
![=10\times 0.1849\times 0.185193\\=0.342421857\\\approx 0.3424](https://tex.z-dn.net/?f=%3D10%5Ctimes%200.1849%5Ctimes%200.185193%5C%5C%3D0.342421857%5C%5C%5Capprox%200.3424)
Thus, the probability of getting two consumers comfortable with drones is 0.3424.

If we write the first integer as the variable n, all numbers that come after it can be written as n+1, n+2, etc.
so the sum of four consecutive integers is:
sum = n + (n+1) + (n+2) + (n+3)
if we simplify:
sum = 4n +6
and if we want to know what the first integer is, we can re-write the equation as:
= n
and that is your answer.
Both 2.5 and -2.5 have absolute values of 2.5. Some nubmers that have a greater absolute value are 3.0, -3, 4.0, -4.
