Answer: -46
Step-by-step explanation:

Using the binomial distribution, it is found that there is a 0.0328 = 3.28% probability that at least 2 of them choose the same quote.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, we have that:
- There are 6 students, hence n = 6.
- There are 20 quotes, hence the probability of each being chosen is p = 1/20 = 0.05.
The probability of one quote being chosen at least two times is given by:

In which:
P(X < 2) = P(X = 0) + P(X = 1).
Then:



Then:
P(X < 2) = P(X = 0) + P(X = 1) = 0.7351 + 0.2321 = 0.9672.

0.0328 = 3.28% probability that at least 2 of them choose the same quote.

Answer:
A: ⅚
B: ⅚
Step-by-step explanation:
City A: 4, 3.5, 5, 5.5, 4, 2
Mean: sum/n
= 24/6 = 4
|x - mean|: 0, 0.5, 1, 1.5, 0 , 2
MAD = sum|x - mean|/n
5/6 = 0.833
City B: 5, 6, 3.5, 5.5, 4, 6
Mean: 30/6 = 5
|x - mean|: 0, 1, 1.5, 0.5, 1, 1
MAD = sum|x - mean|/n
5/6 = 0.833
Answer:
463,488,000,000
Step-by-step explanation:
8.8% = .088
426,000,000,000 * .088 = 37,488,000,000
426,000,000,000 + 37,488,000,000 = 463,488,000,000
