If the situation asks the probability that at least one machine would be working out from 40 can be solved as: 1 divided by 40 then multiplied to 100. From this, we get these values.

1 / 40 = 0.025; then multiplied to 100 will result to 2.5%

So, there's a 1/40 or 2.5% probability that at least 1 machine will work out from 40 machines.
