Set #1 = {A, B, C, D, E, F}
Set #2 = {K, L, M, N, O, P}
There are these two sets of letters, and you are going to pick exactly one letter from each set. What is the probability of picking at least one vowel?	Pick:
A) 1 / 6 B) 1 / 3 C) 1 / 2 D) 2 / 3 E) 4 / 9

Rationale: so not a vowel in set - 1 : 4 / 6 and not a vowel in ser - 2 : 5 / 6 now , 4 / 6 ∗ 5 / 6 = 5 / 9 this is for not a vowel . then for at least one vowel will be = 1 − 5 / 9 = 4 / 9 answer will be e .
Answer: E
