Question

if you roll two dice, what is the probability that their sum will be 7(enter the answer as a fraction in simplest terms.)

Answer 1

7= 1+6
7= 6+1
7= 5+2
7= 2+5
7= 4+3
7= 3+4

So you can get seven in six different ways, which would be :

\[\frac {1} {36} + \frac {1} {36} + \frac {1} {36} + \frac {1} {36} + \frac {1} {36} + \frac {1} {36} = \frac {6} {36} \] = \[\frac {1} {6}\]
