Question $1$

Revisit Later

At an e$-$commerce customer service centre, a total of $112$ complairs were received in one week, and there are only two types of complaints received that week, viz., late Gelivery and poor quality of the $112$ complaints, $78$ were about late delivery of the items and $40$ were about poor quality.

The probability that a customer complaint will be about both late delivery and poor quality.
