Question

jhonyy9 · Answer

so you know that 0,2% of the brake pads that come off of the production line are defective

0,2% = 0,2/100 => 2 /1000

any idea now ?

Probability of at least 4 = 1 - (probability of 0, 1, 2, or 3)
but this question is worded badly
i think it should be there is a 0.2% chance that a brake pad is defective
