Attention for all problems: No need to convert your answer into a percentage for probability of any event. The format is just a fraction and no need to simplify it. Let the sample space be the outcome of rolling a single die: (1,2,3,4,5,6]. n(S)=6 Let the event be rolling an even number. E= (2,4,6] n(E)=3 The probability of the event P(E) =_
