From past experience it has been established that 70 percent of the students who take a course in statistics at QCC pass If you randomly select 6 took what is t?

The question is incomplete. It asks "what is t?" but doesn't define what 't' represents. To answer, we need to know what 't' stands for. Is it:

* The probability that exactly *k* students pass? If so, we'd use the binomial probability formula. We'd need to know the value of *k* (the number of students who pass).

* The expected number of students who pass? This would be 6 * 0.7 = 4.2 students.

* The probability that at least *k* students pass? We'd use the binomial cumulative distribution function (CDF). Again, we'd need the value of *k*.

* The probability that at most *k* students pass? Similar to the above, using the binomial CDF. We'd need the value of *k*.

* Something else entirely?

Please clarify what 't' represents in the context of the problem.
