Plastic parts produced by an injection-molding operation are checked for conformance to specifications. each tool contains 15 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. an inspector chooses 3 part(s) from among the 15 at random. three cavities are affected by a temperature malfunction that results in parts that do not conform to specifications. round your answers to four decimal places. (a) what is the probability that the inspector finds exactly one nonconforming part

0.006593

Step-by-step explanation:

Let K be the number of possibilities that 3 parts can be chosen randomly from among 15.

K is the combination of 15 taken 3 at a time

Of this 455 possibilities of choosing 3 parts, only 3 can have exactly one nonconforming part.  

So the probability of finding three parts with exactly one defective is

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
