a factory produces 10 glass comtainers daily.itmay be assumed that there is a
constant probability p=0.1 of producing a defective container.before these
containers are stored they are inspected and defective ones are set aside.
suppose that there is a constant probalility r=0.1 that a defective container
is misclassified.let X equal the number of containers classified as defective
at the end of a production day.(suppose that all containers which are
manufactured on a particular day are also inspected on that day.) compute
P(X=2)?
a. 0.1937
b. 0.1714
c. 0.2541
d. none of above
我的算法 1. 10C2*0.1^2*0.9^8=0.1937
2. 10C2*0.01^2*0.99^8=0.00415
請問哪個P是正確的 0.1 & 0.01
