Answer:
The answer is:
Step-by-step explanation:
In order to determine the answer, we have to know about scientific notation.
In general the scientific notation is:
where:
a= rational number such that its absolute value has to satisfy:
b= the power of 10 required so that the scientific notation is mathematically equivalent to the original number.
We have to follow the next steps to determine the scientific notation of any number:
- Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is "a".
- Count how many places you moved the decimal point. This number is "b".
- If you moved the decimal to the left, "b" is positive. If you moved the decimal to the right, "b" is negative. If you did not need to move the decimal, "b" = 0.
- Remove trailing 0's only if they were originally to the left of the decimal point.
Finally, the number 0.000000028 written in scientific notation is:

Answer:
There is a 29.27% probability that the flight is overbooked. This is not an unusually low probability. So it does seem too high so that changes must be made to make it lower.
Step-by-step explanation:
For each passenger, there are only two outcomes possible. Either they show up for the flight, or they do not show up. This means that we can solve this problem using binomial distribution probability concepts.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
A probability is said to be unusually low if it is lower than 5%.
For this problem, we have that:
There are 200 reservations, so .
A passenger consists in a passenger not showing up. There is a .0995 probability that a passenger with a reservation will not show up for the flight. So .
Find the probability that when 200 reservations are accepted for United Flight 15, there are more passengers showing up than there are seats available.
X is the number of passengers that do not show up. It needs to be at least 18 for the flight not being overbooked. So we want to find , with
. We can use a binomial probability calculator, and we find that:
.
There is a 29.27% probability that the flight is overbooked. This is not an unusually low probability. So it does seem too high so that changes must be made to make it lower.
