ts of the same species were grown under identical conditions, except for the amount of water they were given. One group was watered with 200 milliliters of water once a day, while the other group was watered with 400 milliliters of water once a day.

Answer:

The height of the plants

Explanation:

In an experimental design, there are two types of variables: independent and dependent variables. The dependent variable is modified by the independent one. In other words, researchers can change the independent variable to see the possible effect in the dependent one. In this example, the study wants to see the effect of the amount of water (independent variable) on plant growth (dependent variable). They evaluate the height of the plants (growth) exposed to different volumes of water. So, the variable of interest in this study is the height of the plants.

A man and a woman have three children, all males. What is the probability that their next child will be a girl?.
ikadub [295]

Given what we know, we can confirm that the couple in question has a 50% chance that their next child will be a girl.

<h3>Why are the odds 1/2 ?</h3>

This has to do with the fact that each child that the couple has is an independent event. While it is true that it is unlikely for the same event to occur many times in succession, the previous events do not influence the outcome of the next child.

Therefore, given that a child can be either male or female when born, the couple in question has a perfect 50% chance for their next child to be a girl.
