In a survey of employee satisfaction, 60% of the employees are male and 45% of the employees are satisfied. What is the probabil
melamori03 [73]

Answer:

The probability of being a male and a satisfied employee is 27%

Explanation:

The probability of being a male P(m) = 60% = 60/100 = 0.6

The probability of being a satisfied employee P(s) = 45% = 45/100 = 0.45

Mathematically, the probability of being a male and satisfied = Probability of being a male * Probability of being a satisfied employee = P(m) * P(s) = 0.6 * 0.45 = 0.27

or simply 27/100 which is same as 27%

Why do you think the United States government was formed as a republic, rather than as a direct democracy?
Fynjy0 [20]

Answer:

The United States is not a direct democracy, in the sense of a country in which laws (and other government decisions) are made predominantly by majority vote.

Explanation:

Some lawmaking is done this way, on the state and local levels, but it’s only a tiny fraction of all lawmaking. But we are a representative democracy, which is a form of democracy.

The United States is also a constitutional democracy, in which courts restrain in some measure the democratic will. And the United States is therefore also a constitutional republic.
