# Math Help - another probability dice

1. ## another probability dice

If you roll a loaded die where the even numbers come up twice as often as the odd numbersfind the probability of each of:
Can someone check my answers please: Thank you.
{1 22 3 44 5 66} 9 outcomes
P(1)=1/9 P(2)=2/9

P(3)=1/9 P(4)=2/9
P(5)=1/9 P(6)=2/9
P(5 | odd)= not sure ?? 1/9 {rolling a 5 given that theroll was an odd number}

2. ## Re: another probability dice

The only way to get an odd roll is one of each. If the total is 5, you have only (1,4), and (2,3)

I think that the question involves tossing only one die.
$P(odd)=\tfrac{1}{3}$ and $P(5\cap odd)=P(5)=\tfrac{1}{9}$.

So $P(5|odd)=~?$
