Answer:
0,3% and 0,003
Step-by-step explanation:
To make it as a percent, remeber that you need to transform this fraction to \frac{something}{100}
Therefore, we can divide 1000 by 10, to get the 100.
So we have:
\frac{3}{1000} / 10 = \frac{3 / 10}{1000 / 10} = \frac{0,3}{100}
Note: 3 / 10 is 0,3 (you move the comma to the left as much zeros)
and 1000 / 10 is 100 (you cut the zeros)
As we know have a fraction that is 100 on the denominator, we assume that \frac{0,3}{100} is 0,3%
Now, to get the fraction as decimal, just use the same hint I gave in the other part of the exercise (you move the comma to the left as much zeros).
Therefore, \frac{3}{1000} is 0,003

Answer:
There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Desired outcomes:
The number of male nannies selected. 24 of the nannies placed were men. So the number of desired outcomes is 24.
Total outcomes:
The number of nannies selected. 4,176 nannies were placed in a job in a given year. So the number of total outcomes 4176.
Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
