Ruffer · Answer 1

91.79% probability that he or she is a male or a civilian employee is

Step-by-step explanation:

We have these following probabilities:

69.6% probability of a full-time law enforcement officers being a sworn officer.

Of those, 88.2% probability of them being males.

100 - 69.6% = 30.4% probability of a full-time law enforcement officers being a civilian employee.

Of those, 60.8% probability of them being females.

The probability that he or she is a male or a civilian employee is:

That is, civilian employees or male sworn officers work.

0.304 + 0.882*0.696 = 0.9179

91.79% probability that he or she is a male or a civilian employee is

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
