Answer:
There is a 93.28% probability that one cubic meter of discharge contains at least 6 organisms.
Step-by-step explanation:
The number of organisms in a cubic meter of discharge is a Poisson process. So, we use the following definition:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
is the Euler number
is the mean in the given time interval.
Organisms are present in ballast water discharged from a ship according to a Poisson process with a concentration of 10 organisms/m3. This means that
What is the probability that one cubic meter of discharge contains at least 6 organisms?
This is . We know that either we have less than 6 organisms, or we have at least 6 organism. The sum of the probabilities is decimal 1. So
In which
.
Each one of these probabilities can be found by the poisson formula.
So
So
Finally
There is a 93.28% probability that one cubic meter of discharge contains at least 6 organisms.
(a)
different possibilities
(b)
So, there is a 1 in 4 chance that both dice will show an even.
Answer:
Idk I send you the solution to those questions but taking as a reference the points of the image, I hope you can see this early so you can tell me if I do the same with the points at the end
Answer:
P = 180 cm.
Step-by-step explanation:
Perimeter = 2 Lengths + 2 Widths
P = 2l + 2w
P = (2 * 40) + (2 * 50)
P = 80 + 100
P = 180 cm.
