    S = sample space

    S = set of all possible outcomes

    S = {1,2,3,4,5,6}

    E = event space

    E = set of items we want to happen (rolling a 5, or rolling an odd number)

    E = {1, 3, 5}

    note: the event of "rolling a 5" is a subset of "rolling an odd number" because 5 is odd

    n (S) = number of items in the sample space

    n (S) = 6

    n (E) = number of items in event space

    n (E) = 3

    Divide the values to get the probability

    P (E) = n (E) / n (S)

    P (E) = 3/6

    P (E) = 1/2

    P (E) = 0.50

    P (E) = 50%

    The answer in fraction form is 1/2

    The answer in decimal form is 0.50

    The answer as a percentage is 50%

    These three values all represent the same idea, just written in different forms.

    note: writing "P (E) " means "the probability of event E occurring", which I've defined as the event space above
