According to the general equation for conditional probability, if p (a^b')=1/6 and p(b')=7/12 , what is the value of p(a[b)?
Alex
P(B) = 1 - P(B') = 1 - (7/12) = 5/12 <span>P(A∩B)=<span><span>P(A∩<span>B′</span>)/</span><span>P(<span>B′</span>) </span></span>× <span><span>P(B)/</span>1

</span></span>Plugging values into the last equation we get: <span>P(A∩B)=<span><span>1×12×5 / </span><span>6×7×12 </span></span>= <span>542</span></span>
Now we can make use of the following formula <span>P(A|B)=<span><span>P(A∩B) / </span><span>P(B)</span></span></span><span> by plugging in the values that we have found.
</span>
<span>5/42 is the numerator and the denominator is 5/12.
</span>

The bottom (denominator) is P(B) which equals 5/12.

<span>P(A|B)=<span><span>5×12 / </span><span>42×5 = 6/210

6/210 = 2/7

</span></span></span><span>p(a[b]) = 2/7</span>

When glucose is converted to ethanol by yeast (as in the production of beer) how much of the chemical energy that was originally
aniked [119]

Answer:

<h2>92%</h2>

Explanation:

When glucose is converted to ethanol by yeast, one mole of glucose is converted  into two moles of ethanol and two moles of carbon dioxide,  

and this process produce two moles of ATP.  

C6H12O6 → 2 C2H5OH + 2 CO2

When glucose is converted to ethanol by yeast (as in the production of beer) 92% of the chemical energy that was originally stored in glucose still remains in the end product, ethanol, that is produced.
