Calculator allowed

A collection of counters is classified by colour and shape

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

Let A be the event that the counter is blue, and let B be the event that the counter is round. The sample space is S

The sample space S contains the whole-number labels 1 to 32, inclusive

\[A = \{1, 2, 3, 4, 5, 6, 7, 8, 18, 19, 20, 21, 22, 23, 24, 25, 26\}\]
\[B = \{9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26\}\]
(a)1 mark

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

(b)1 mark

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