Anyone know the answer? Also could you put down what equation I’m supposed to use?

goldenfox [79]

Answer:

The bottom two are your answers.

Step-by-step explanation:

What you do is use the slope formula which is y_2-y_1/x_2-x_1.

So for PQ it will be 12(which is y_2)-6(which is y_1)/4(which is x_2)-5(which is x_1) which equals -6.

12-6/4-5=-6.

According to the general equation for conditional probability, if P(A n B) = 3/4 and P(B) = 4/5 what is P ( A|B)?

leonid [27]

Given:

$P(A\cap B)=\dfrac{3}{4}$

$P(B)=\dfrac{4}{5}$

To find:

The $P(A|B)$ .

Solution:

Conditional probability:

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}$

Substituting the given values, we get

$P(A|B)=\dfrac{\dfrac{3}{4}}{\dfrac{4}{5}}$

$P(A|B)=\dfrac{3}{4}\times \dfrac{5}{4}$

$P(A|B)=\dfrac{16}{16}$

Therefore, the correct option is B.
