A shipment has 22 products, of which 3 are defective. Three people in turn pick up, each person picks up a product at random (no
n-refundable). Calculate the probability that out of the three people who come in to pick up at least one person picks up a waste product.
1 answer:
Answer:
Probability of no one picking up a defective product = 571 / 1540
Step-by-step explanation:
Total number of items = 22
non-defective items = 22-3 = 19
Probability of all three picking up non-defective products
= 19/22 * 18/21 * 17/20
= 969/1540
Probability of at least one picking up a defective product
= 1 - 969/1540
= 571/1540
(=0.371, approx.)
