Answer:
Dilation
Step-by-step explanation
In geometry, a transformation that enlarges or reduces a polygon by a certain scale factor around a particular center point is called dilation. A scale factor is the amount by which an image grows or shrinks .In this case, dilution requires us to multiply initial dimensions by the scale factor to obtain the dimensions of the image.
Using the binomial distribution, it is found that there is a 0.5 = 50% probability of selecting a two-child family with one boy and one girl.
For each child, there are only two possible outcomes, either it is a boy, or it is a girl. The probability of a child being a boy or being a girl is independent of any other child, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- Two children, hence .
- Equally as likely to be a boy or a girl, hence .
The probability of one of each is P(X = 1), hence:
0.5 = 50% probability of selecting a two-child family with one boy and one girl.
