B2. Consider a quality control inspection. There are 10 products in each box, the number of defective products is randomly distributed from 0 to 2 with an equally likely possibility. When we do the open-box inspection, a product will be selected randomly from each box. If the inspected product is defective, then the whole box of products will be considered below standard and will be destroyed. a) What is the probability of a box of products that passes the acceptance? Give your answer to two decimal places. b) If a box of products passes the acceptance, what is the probability that there is no defective in this box? Give your answer to two decimal places.

Question
B2. Consider a quality control inspection. There are 10 products in each box, the number of
defective products is randomly distributed from 0 to 2 with an equally likely possibility.
When we do the open-box inspection, a product will be selected randomly from each box.
If the inspected product is defective, then the whole box of products will be considered
below standard and will be destroyed.
a) What is the probability of a box of products that passes the acceptance? Give your
answer to two decimal places.
b) If a box of products passes the acceptance, what is the probability that there is no
defective in this box? Give your answer to two decimal places.
