Answer:

$(B) P(B)=\dfrac{16}{31}$

Step-by-step explanation:

From the Venn diagram, n(AUB)=31

The given probabilities in the option are calculated below:

$P(A)=\dfrac{21}{31}\\\\P(B)=\dfrac{16}{31}\\\\P(A|B)=\dfrac{P(A\cap B)}{P(B)}= \dfrac{6/31}{16/31} =\dfrac{6}{16}=\dfrac{3}{8} \\\\P(B|A)=\dfrac{P(B\cap A)}{P(A)}= \dfrac{6/31}{21/31} =\dfrac{6}{21}=\dfrac{3}{7}$

The only correct option is the probability of B which is $\frac{16}{31}$

What is a related equation to this equation?

Brilliant_brown [7]

Simple.....

you have $\frac{18}{a} =7
$

to find what a is....simplify/multiply both sides....

$a* \frac{18}{a} =7*a$

simplifying it too....

18=7a

$\frac{18}{7} = \frac{7a}{7}$

$\frac{18}{7} =a$

Thus, your answer, C.

Hello!

To check your work what you do is you put 3 in for x and 7 in for y and see if you get the same answer on both equations.

Hope this helps!
