Binomial distribution. Probability of exactly k successes in n independent trials where p is the probability of success for any given trial:



Where

Your n is 12, your k is 6, and your p is 0.26

Plug in the numbers and do the arithmetic.

Or save yourself some time: Open a blank Excel sheet and pick a cell. Type =BINOMDIST(6,12,0.26,FALSE). When you hit Enter, you will have your answer.
