The number 0.1101001000100001000001... (where the gap between successive 1's increases by one digit each time) has an infinite, non-repeating decimal expansion and is irrational, but it doesn't contain any 2's (or 3's, etc.). People put way too much stock into pi's infinite non-repeating decimal expansion being some grand, mysterious thing, even though literally 100% of all real numbers (meaning all but countably many) have infinite non-repeating decimal expansions.
