Concept explainers
Whether the events are independent or dependent and the probability for someone ordered item #345A also ordered item #345B.
Answer to Problem 22PR
Events are dependent.
The probability for someone ordered both the items is approx. 0.28.
Explanation of Solution
Given information:
18% of INET Clothing customers purchased item #345A.
5% of the customers order item #345A and item #345B.
Conditional Probability definition:
Since there are some customers ordered both the items, the events are dependent.
Now,
Probability for the customer purchased item #345A,
Probability for the customer ordered item #345A and item #345B,
Then
Apply the conditional probability:
Thus,
Around 28% of the customers ordered item #345A and item #345B and the probability is approx. 0.28.
