A student taking a MC exam with 6 QQ's in which each equation has 4 options, and the student selects the options randomly. What is the probability that she will get 6 qq's correct? Round to 4 decimal places as needed. Can someone please explain to me, on how to work this out? I'm quite confused ~~". 0.25% chance in getting one qq right. X6?

If A has probability p and B has probability q, the probability of A and B is pq: p times q. Whoever gave you this problem clearly expects you to know that.
