Calculator allowed

A collection of parcels is classified by two labels

One of the listed outcomes or recorded items is selected uniformly at random

Let A be the event that the parcel has a local-delivery label, and let B be the event that the parcel has a fragile label. The sample space is S

The sample space S contains the whole-number labels 1 to 19, inclusive

\[A = \{1, 2, 3, 4, 5, 6, 7, 16, 17\}\]
\[B = \{8, 9, 10, 11, 12, 13, 14, 15, 16, 17\}\]
(a)1 mark

Which event is known in \(\Pr(B\mid A)\)?

(b)1 mark

Calculate \(\Pr(B\mid A)\)
