The central limit theorem in statistics states that, given a sufficiently large sample size, the sampling distribution of the mean for a variable will approximate a normal distribution regardless of that variable’s distribution in the population. Unpacking the meaning from that complex definition can be difficult.

Use the distribution of its random variable. If you are being asked to find the probability of the mean of a sample, then use the CLT for the mean.
