Recall the property of probability distributions that for a
sample space
S =
{s1, s2, , sn},
we have
P(s1) + P(s2) + + P(sn) = 1.
In other words, probabilities of all the outcomes (rolling
a 1, or a 2, or a 3, or a 4, or a 5, or a 6) will sum to 1. Use
this fact to write an equation in terms of x, and
solve for x.
