I need help with question 5 and 6 please.

The half-life of Po-211 is approximately 500ms (half a second). Without using the PhET model, sketch a pie graph indicating the number of undecayed Po-211 atoms for a reaction starting with 100 total atoms. t=0 is not shown, but would be 100 atoms. t=0.5st=1.0st=1.5st=2s Now, simulate the decay of 100 Po-211 atoms by adding 100 atoms from the "Bucket o' Polonium". Click on "add ten" ten times very quickly. You should be able to get 100 in the bucket before it gets to .5s when you should pause the simulation. Sketch what the pie graph looks like at the times shown. You can also do: Cntrl prtsc (control printscreen) and paste the picture in. t=0.5st=1.0st=1.5st=2s 5. Compare your prediction to the results that you observed. How can you explain any discrepancies? Compare your prediction to the results that you observed. How can you explain any discrepancies? 7 The half life is predictive, but there will be some variation from the smooth decay graph in reality. This is just randomness. If you start with 10 atoms of Polonium, which will be more likely, that you have 9 atoms 0.5s later or that you have 4 atoms 0.5s later? Explain
