Question

probability winning is ¾, what are the odds of winning of An quality control procedure for testing disposable cameras consists of diawing two cameras at random from a lot of 100 without replacing the first camera before drawing the second. If both are defective, the entire lot is rejected.C The lot contains 7 detective cameras (7% are defective). What is the probability of getting two defective cameras - (the lot being rejected). cda b) Suppose the same procedure is done with a lot of 800 with 56 defective (7% defective). We are asked to pick two cameras: replace the first and the scramble - with replacement. Find the probability of getting at least one normal cameras - (the lot being accepted). Admittedly tricky In February 2017, Samford University conducted a poll on the status of VE at the University. The question was asked: "Which of the following, if any, lon to rend or give [primary gift] to your wife or girlfriend for Valentine's

Explanation / Answer

a) total item = 100

total defective = 100*0.07 = 7

required probability = 7C2 /100C2

= 0.00424242

b)

total item = 800

defective = 56

with replacement

Probability of getting at least one normal = 1 - Probability of getting both defective

= 1 - 0.07^2

= 0.9951
