Set #1 = {A, B, C, D}
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?	Choose the most appropriate option:
A) 1/6 B) 1/3 C) 3/8 D) 2/3 E) 5/6
So Not a vowel in Set-1 : 3/4   And not a vowel in Ser-2:5/6   Now,   3/4∗5/6=5/8   This is for not a vowel.   Then for at least one vowel will be = 1−5/8=3/8   Answer will be 3/8.
