The probability that a three shows on at least one of the dice is 11/36.
<h3>How to calculate the probability?</h3>
It should be noted that of probability means the likelihood of the occurence of an event.
The probability that a three shows on at least one of the dice will be:
= 11/36
This can be seen from the table that is attached.
The probability that the total is less than 8 will be:
= 21/36
= 7/12
Here, there are 21 places where the total is less than 8.

65.27mm of acid is present in solution.
Step-by-step explanation:
Given,
Quantity of solution = 333mm
Acid Percentage = 19.6%
Quantity of acid = 19.6% of Quantity of Solution
![Quantity\ of\ acid=\frac{19.6}{100}*333\\Quantity\ of\ acid=\frac{6526.8}{100}\\Quantity\ of\ acid=65.27mm](https://tex.z-dn.net/?f=Quantity%5C%20of%5C%20acid%3D%5Cfrac%7B19.6%7D%7B100%7D%2A333%5C%5CQuantity%5C%20of%5C%20acid%3D%5Cfrac%7B6526.8%7D%7B100%7D%5C%5CQuantity%5C%20of%5C%20acid%3D65.27mm)
