Outcomes

1.3.9

review probability as a measure of β€˜the likelihood of occurrence’ of an event

1.3.10

review the probability scale: 0 ≀ 𝑃(𝐴) ≀ 1 for each event 𝐴, with 𝑃(𝐴) = 0 if 𝐴 is an impossibility and 𝑃(𝐴) = 1 if 𝐴 is a certainty

1.3.11

review the rules: 𝑃(A Μ… ) = 1 βˆ’ 𝑃(𝐴) and 𝑃(𝐴βˆͺ𝐡) = 𝑃(𝐴) + 𝑃(𝐡) βˆ’ 𝑃(𝐴∩𝐡)

1.3.7d

use set langauge and notation for events: recognise mutually exclusive events
