Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.

\bf TW-TX=XW\implies \cfrac{8a}{5}+\cfrac{1}{10}-\left(a +\cfrac{4}{5} \right)=XW
\\\\\\
\cfrac{8a}{5}+\cfrac{1}{10}-a-\cfrac{4}{5}=XW\implies \cfrac{3a}{5}-\cfrac{7}{10}=XW\\\\
-------------------------------\\\\

\bf TX:XW\qquad 2:1\qquad \cfrac{TX}{XW}=\cfrac{2}{1}\implies \cfrac{a+\frac{4}{5}}{\frac{3a}{5}-\frac{7}{10}}=\cfrac{2}{1}
\\\\\\
\cfrac{\frac{5a+4}{5}}{\frac{6a-7}{10}}=\cfrac{2}{1}\implies \cfrac{5a+4}{5}\cdot \cfrac{10}{6a-7}=\cfrac{2}{1}\implies \cfrac{10a+8}{6a-7}=\cfrac{2}{1}
\\\\\\
10a+8=12a-14\implies 22=2a\implies \cfrac{22}{2}=a\implies 11=a

OlgaM077 [116]

Answer:

G

Step-by-step explanation:

"Any particular event either (a) will happen or (b) won't happen."

That statement above is a certainty, probability = 100% = 1

This means the probability that event E <u>will </u>happen plus the probability that even E <u>won't </u>happen must add up to 100% = 1

So we can always say -->  prob(E) + prob (not E) = 1

The probability you will roll a 5 on a fair, six-sided die is 1/6.

So we use that to find the probability of not rolling the 5.

1/6 + prob(not E) = 1

   prob(not E) = 1 - 1/6  <---- This is answer G

    prob(not E) = 5/6

Hope this helps.
