Please Help! I don't understand this question... (I will mark brainliest)
Rina8888 [55]

Interesting question.

It will describe a multi step proof if the givens have to be restated.


It does depend on theorems and postulates or could.


Geometric statements require that they logically fall into the pattern needed for a proof. This statement is also true.


But the best answer is D. If you provide 1 counterexample, you don't need to go any further. <<<<< Answer.

m_a_m_a [10]

Answer:

The probability that the selected person is a woman engineering major is 0.0396.

Step-by-step explanation:

The proportion of students at the university who are women is 0.42.

<em>P (W) = 0.42</em>

The proportion of students at the university who are engineering majors is 0.18.

<em>P (E) = 0.18</em>

The proportion of engineering majors that are women is 0.22.

<em>P (W|E) = 0.22</em>

The proportion of students at the university that are woman and engineering major is:

P (W|E)=\frac{P(W\cap E)}{P(E)} \\P(W\cap E)=P(W|E)\times P(E)\\= 0.18\times0.22\\=0.0396

Thus, the probability that the selected person is a woman engineering major is 0.0396.
