Probability 30311

There are 200 components in the production batch, of which 26 have a plus deviation from the nominal value. Calculate the probability that none of the 10 products selected will have a positive variance if we make selections without repetition

Correct answer:

p =  0.2484

Step-by-step explanation:

C0(10)=(010)=0!(100)!10!=11=1 n=200 n1=26 n2=10  p1=n1/n=26/200=10013=0.13  p=(0n2) p10 (1p1)n20=1 0.130 (10.13)100=0.2484
