Conditional probability from exact representations
A collection of tickets is classified by two recorded properties
One of the listed outcomes or recorded items is selected uniformly at random
Let A be the event that the ticket is for a morning session, and let B be the event that the ticket was booked online. The sample space is S
The sample space S contains the whole-number labels 1 to 19, inclusive
\[A = \{1, 2, 3, 4, 5, 9, 10, 11, 12, 13\}\]
\[B = \{6, 7, 8, 9, 10, 11, 12, 13\}\]
