There is one way to make a 2 or a 12
There are two ways to make a 3 or 11
There are three ways to make a 4 or 10
There are five ways to make a 5 or 8
There are four ways to make a 6 or 9
There are six ways to make a 7
There are a total of 36 possibilities. 15 (1 + 2 + 3 + 4 + 5) of these possibilities are less than 7 and therefore, 21 ways are 7 or greater.
The probability that less than 7 is rolled is 
The probability that less than 7 IS NOT rolled is then one minus the probability that less than 7 IS rolled. You can do your own arithmetic.
