    Probability

    My question is ;
    A 6 six sided die is rolled. Find the probability of rolling a 3 OR a five.

    Please tell me if I ahve this right if not please post what is the proper way to figure this out
    P(Roll a 3) + P(rolla a 5)
    (roll a 3) Probability is 1 out of 6 ......1/6
    (roll a 5) Probability is 1 out of 6.......1/6
    SO 1/6 + 1/6 = 2/6 = 2/6 or .333

    IS THIS CORRECT?
