If 1.5% of the bolts made by an automotive factory are defective, what is the probability that in a shipment of 200 bolts, there are 6 defective bolts? Place your answer, rounded to four decimal places, in the blank.

prob (defective) = .015
prob(not defective) = .985
prob (6 of 200 defective)
= C(200,6) (.015)^6 (.985)^194
= .0500
