In a shipment of 400 parts, 14 are found to be defective. How many parts out of 1000 would NOT be defective? Can you please show a proportion I am confused.

965 parts would not be defective.

Step-by-step explanation:

So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.

386/1 * 5/2

193/1 * 5/1

965/1

That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

probability for j is 1/4

while

a is 1/6

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