Hint: There are 12 numbers. Half of them are less than 7. I know this because I took 10 seconds to count them.

Basic definition of probability; what don't you understand about the problem?

There are 12 equally likely outcomes; 6 of them (1 through 6) are less than 7. The probability is 6/12.

Simplify the fraction, or convert to a percentage, if required.
