Answer:
Step-by-step explanation:
Given: Equation is
To find: flaw in Gwendolyn's work and the correct solution to the equation.
Solution:
In the given question,
the first step is
The second step is
(This step is obtained on multiplying by
)
The third step is
This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:
So, the correct solution is
Answer:
Option c) Sample space
Step-by-step explanation:
Given that a family has two children.
Let M represents male, and F represents female.
In probability theory, the sample space (also called sample description space or possibility space) of an experiment or random trial is the set of all possible outcomes or results of that experiment. A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S, , or
(for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.
Let S be the sample space of the given data.
Here the sample space is typically the set {male, female}, commonly written
ie, S is the set or
For the gender of the children, corresponding sample space would be , commonly written as
S is the set or
