    Probability of rolling an even number means the desired outcome is 2, 4, or 6. This is a mutually exclusive event, since we can't land on 2, 4, or 6 at the same time. Therefore, add the probabilities of each. 1/6 + 1/6 + 1/6 = 3/6 simplify to 1/2

    to calculate the probability, you have to write a fraction with desired outcome/total possible outcomes

    for the denominator, what are the total possible outcomes when rolling a die?

    if we want an even number as our desired outcome, then there are only 3 possibilities of that happening (2, 4, or 6). Put that 3 over the total possible outcomes (6). 3/6 is your answer

    3/6 can be reduced to 1/2
