Graphing the probability that a machine still works
If you were a supervisor at the factory with the unreliable machine, you might want to understand how likely the machine is to keep working over time. In this exercise, you'll plot the probability that the machine is still working across the first 30 days.

Instruções do exercício
- Calculate a vector of probabilities of whether the machine is still working on each day from day 1 to 30, and save it as
still_working. You can do this with a single call topgeom()by passing in a vector of numbers as the first argument. The machine has a 10% chance of breaking each day. - Run the command
qplot(still_working)to graph the probability of the machine still working on each of the first 30 days, with the day on the x-axis and the probability on the y-axis.
