As of a certain date, 94,696 of the four-character sequences using either letters or digits had not yet been claimed. If a four-character name is randomly selected on that date, what is the probability that it is already owned? (Round your answer to four decimal places.)

Ответ:
Hence the probability that are already owned are 0.943620
Step-by-step explanation:
Given:
No fo character sequences using either letter or digits had not been claimed=94696
To find :
What is probability that letter are already claimed ?
Solution:
We know that there are 26 alphabets and digits are 0,1,2.. 9
Hence total will be of 36.
Now we are going to Arrange the sequence for all possible values
as there 4 characters we get ,each of them with 36 possible values
=36*36*36*36
=36^4
=1679616.
Now we have a sequence with 94696 character and digits are not claimed .
Its probability
=94696/1679616
=0.05637.
So the required probability will be ,
P(claimed)=1- P(Not claimed)
= 1-0.056379
=0.943620
Hence the probability that are already owned are 0.943620
Ответ:
b = d -wn
Step-by-step explanation:
b = d -wn
Here, n is an independent variable and b is an dependent variable in an linear relation, and d and w are two constant values.
Hope it will find you well.
