Probability of a loaded die

  1. Mar 27, 2016 #1
    1. The problem statement, all variables and given/known data
    (10 points) Consider a six-sided die that is loaded so that numbers 2, 3, 4, 5 and 6 are all equally likely to appear, and 1 is three times as likely to appear as 2.
    (a) What is the probability of rolling a 2?
    (b) What is the probability of rolling a 1?
    (c) What is the probability of rolling an even number?

    2. Relevant equations

    3. The attempt at a solution
    3p+p+p+p+p+p=8p
    P(1)=3/8
    P(2)=1/8
    P(3)=1/8
    P(4)=1/8
    P(5)=1/8
    P(6)=1/8
    a)1/8
    b)3/8
    c)3/8
    Okay these answers seem way to0 simple for a 10 point question, what did I do wrong?

    Nothing is wrong.

    Anyway, I guess you mean "too simple", not "to simple".
