Acompany has 200 machines. each machine has 12% probability of not working.1) if you were to pick 40 machines randomly, the probability that 5 would not be working 2) the probability that all would be working 3) and the probability that at least one machine would be working

1) This probability is given by

... C(40,5)·0.12⁵·0.88³⁵ ≈ 0.18665 . . . . . where C(n, k) = n!/(k!(n-k)!)

2) This probability is given by

... 0.88⁴⁰ ≈ 0.00602

3) This is the complement of the probability that all have failed.

... 1 - 0.12⁴⁰ ≈ 1.0000

i belive those are the ones that are under 90 degreese.
