An inspector samples four pc’s from a steady stream of computers that is known to be 12% nonconforming. what is the probability of selecting two nonconforming units in the sample? write your answer to 3 decimal places in the format: x. xxx

0.067

Step-by-step explanation:

Binomial distribution formula :-

, here P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.

Given : n = 4 , p = 12 % = 0.12 and x =2

Then ,

∴ The probability of selecting two nonconforming units in the sample = 0.067

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
