So just to cut to the chase, power is a probability. You can view it as the probability that you're doing the right thing when the null hypothesis is not true. And the right thing is you should reject the null hypothesis if it's not true. So it's the probability of rejecting, rejecting your null hypothesis given that the null hypothesis is false. So you could view it as a conditional probability like that. But there's other ways to conceptualize it. We can connect it to type two errors.
