Ans. A normal

Skewness is a measure of the asymmetry of probability distributions. Negative skew or left skew has fewer low values and a longer left tail, while positive skew has fewer right values and a longer right tail.

By the Central Limit Theorem, for large n, the distribution of X should be approximately Normal.
