Answer:
0.7588 = 75.88% probability that more than 1 vessel transporting nuclear weapons was destroyed
Step-by-step explanation:
The vessels are destroyed without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Fleet of 17 means that
4 are carrying nucleas weapons, which means that
9 are destroyed, which means that
What is the probability that more than 1 vessel transporting nuclear weapons was destroyed?
This is:
In which
So
Then
0.7588 = 75.88% probability that more than 1 vessel transporting nuclear weapons was destroyed
