Question on determining the expected value and variance

Consider a fair 6-sided die and let X be the number of times the die must be rolled in order for all 6 sides to eventually come up.

a.) Determine E(X)and V(X).

b.) If you model X as a normal distribution, determine the probability that all 6 sides will eventually come up in under 22 rolls of the die.
