Four friends decide to go to McDonald’s. It was reported that the location they visited filled approximately 90.9% of the orders correctly. What is the probability that none of the orders will be filled correctly? Which probability model should you use to calculate the answer?

0.0069% probability that none of the orders will be filled correctly, using the binomial probability distribution.

Step-by-step explanation:

For each order, there are only two possible outcomes. Either it is filed correctly, or it is not. The probability of an order being filed correctly is independent from other orders. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

This means that

What is the probability that none of the orders will be filled correctly? Which probability model should you use to calculate the answer?

This is P(X = 0).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[\tex]

[tex]P(X = 0) = C_{4,0}.(0.909)^{0}.(0.091)^{4} = 0.000069[\tex]

0.0069% probability that none of the orders will be filled correctly, using the binomial probability distribution.

i dony know

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
