Given parameters:
Percentage of enrollment of 3-year-olds = 40%
Unknown:
Probability that a randomly selected 3-year-old is enrolled in a day care = ?
Probability is the likelihood of an event to occur.
Probability = 
In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.
We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.
The possible enrollment is 40 and the total is 100;
Input the parameters and solve;
Probability =
=
The probability that any randomly selected 3 year old is enrolled in day care is 
Answer:
0.16
Step-by-step explanation:
The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:
Here the standard deviation is

= 1.72
Now the minimum no of smokers is

B, there is no angles so it has to be SSS
The scale for the second values is 56/8 = 7
C = 3 x 7 = 21
C= 21
Answer:
No.
Step-by-step explanation:
Plugging in g(x) into f(x), you don't get x. g(x) would need to be =
