Answer:
0.2384 = 23.84% probability that 3 were laser printers.
Step-by-step explanation:
The printers will be chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
In which:
x is the number of sucesses.
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:
20 orders means that
8 were laser printers, which means that
Sample of 5 means that
What is the probability that 3 were laser printers?
This is P(X = 3).
0.2384 = 23.84% probability that 3 were laser printers.
1.) 4^3= 64
2.) a^2 + b^2=c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169= c^2
3.) a^2 + b^2 = c^2
24^2 + b^2 = 26^2
576 + b^2 = 676
b^2 = 100
2.) a^2 + b^2=c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169= c^2
3.) a^2 + b^2 = c^2
24^2 + b^2 = 26^2
576 + b^2 = 676
b^2 = 100
