Answer:
The numbers are 9, 19 and 76.
Step-by-step explanation:
Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.
The first number in terms of x:
The second number in terms of x:
If we add them all up, these 3 numbers in terms of x must be equal to 104, so:
Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:
The first number is 9, second number 19 and the third number 76.

Answer:
The probability that he or she is a male or a civilian employee is 1.037068
Step-by-step explanation:
Probability of sworn officers = 0.696
Probability of civilians = 1 - 0.696 = 0.304
Probability of male sworn officers = 0.882*0.696 = 0.6139
Probability of male civilian = (0.304*(1-0.608)) = 0.1192
Hence probability that he or she is a male or civilian employee is
0.6139 + 0.1192 + 0.304 = 1.037068
