The probability that your homework is on disc i is 12.25%.
<h3><u>Probabilities </u></h3>
Given that the disc containing the only copy of your homework just got corrupted, and the disk got mixed up with two other corrupted discs that were lying around, and it is equally likely that any of the three discs holds the corrupted remains of your homework, and your computer expert friend offers to have a look at one of the discs, and you know from past experience that his probability of finding your homework from a disc is 0. 35, given that the homework is in there, given that he searches on disc 1 but cannot find your homework, to determine what is the probability that your homework is on disc i, for i = 1, 2, 3, the following calculation must be performed:
- Disc i = 0.35 x 0.35
- Disc i = 0.35^2
- Disc i = 0.1225
- 0.1225 x 100 = 12.25
Therefore, the probability that your homework is on disc i is 12.25%.

The question is incomplete, the complete question is;
Use the chemical reaction to answer the question. CaCO3 → CO2 + CaO A scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction shown. What is the total mass of the products?
A. 10 grams B. 15 grams C. 30 grams D. 60 grams
When a scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction, the total mass of the products is 30 grams.
According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction.
The simple interpretation of this law is that the total mass of reactants should necessarily be the same as the total mass of products obtained in the reaction.
We had 30grams of Calcium Carbonate (CaCO3) reacting hence we must have a total mass of 30 grams of CaO and CO2 obtained after reaction.
