this simulation shows how we can tell what will happen if a disease spreads and we can do tests without anybody being sick with time. for example with blue and pink dots the pink shows the non-sick people and the blue people are the suck ones when we do nothing with 10, 100, 250 examples it will test the spread. to start the simulation we shal press the green flag and when satisfied and want to stop press the red octagon.then go in the code and change the 10 to 100 then 250. when you have finished the simulation you should have gotten your trials or tests done and maybe got the average time also. once the average time has been found for each group of population whichever one had the slowest average time for getting sick is that population is going the be the longest time for that group to get sick.
