I tried as follows:

1+2=3

p(1)=1/8

p(2)=1/8

1/8 * 1/8= 1/64

Question 2:

You select 3 numbers at random from 1,2,3,4,5,6,7,8,9. What is the probability that the sum of 3 numbers is 6?

I tried as follows:

1+2+3=6

or

2+1+3=6

or

3+2+1=6

or

2+2+2=6

p(1)=1/9

p(2)=1/9

p(3)=1/9

1/9 * 1/9 *1/9 = 1/729

Am I going in wrong path? Please correct me.
