Conditional probability from exact representations
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 22, inclusive
\[A = \{1, 2, 3, 4, 12, 13, 14, 15, 16, 17, 18, 19, 20\}\]
\[B = \{5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20\}\]
