12.1.1 If a person is selected at random, determine the probability that it will be a female with green eyes. (2) 12.1.2 After analysing the results, a grade 11 learner concludes that the probability of having green eyes is independent of gender. Is he correct? Substantiate your answer with relevant calculations. Give all answers
o Probability lies between 0 (impossible event) and 1 (certain event) o If P(Event) = 1 means that it will definitely occur o If P(Event) = 0 means that it is an impossible event o If all events are equally likely, then the probability of the event is: 𝑃𝐸 = 𝑃( 𝐸 )

9. The probability that an event (or outcome) does not occur is called the complement of a probability, and is written as either ‘~E’ or ̅ where E refers to the event. In this case, E refers to the spoon coming to rest in the 'up' position. Therefore, the probability that the spoon would not land 'up' is: 𝑷( ̅)= −𝑷( )
