Conditional probability from exact representations
A collection of labels is classified by shape and printing
One of the listed outcomes or recorded items is selected uniformly at random
Let A be the event that the label is rectangular, and let B be the event that the label has a barcode. The sample space is S
The sample space S contains the whole-number labels 1 to 30, inclusive
\[A = \{1, 2, 3, 4, 5, 6, 7, 8, 18, 19, 20, 21, 22, 23, 24\}\]
\[B = \{9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24\}\]
