Monte Carlo simulation

Is it mandatory that each simulation trial depends on previous trial in Monte Carlo simulation ?

So does that makes the following statement incorrect or correct ?

"In Monte Carlo simulation, each simulation trial is dependent upon the result of the previous trial."

I am learning about Monte Calro simulations and trying to answer this question in which I only have this statement:

"In Monte Carlo simulation, each simulation trial is dependent upon the result of the previous trial."

so this is true or false ?

Can someone help me to solve this problem

A market survey company wants to study the investment in a detergent factory based
on three factors. These factors are
Independent of each other. The probability distribution of each are

Annual Demand Profit/Unit Required Investment
Units Probability Rs. Probability Rs. Probability
20 0.05 3.00 0.10 1,750.00 0.25
25 0.10 5.00 0.20 2,000.00 0.50
30 0.20 7.00 0.40 2,500.00 0.25
35 0.30 9.00 0.20
40 0.15 10.00 0.10
45 0.15
50 0.05

Use Monte-Carlo simulation for 1000 iterations and estimate the ROI percentage based on profit
{(Profit*Demand)/Investment}
