Set #1 = {J, K, L, M, E}
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? Options
A) 1/6 B) 1/8 C) 1/3 D) 1/4 E) 1/9
At least questions are best solved by taking the opposite scenario and subtracting it from 1. Probability of choosing no vowel from set 1 is 4/5 and set 2 is 5/6. Multiply these to get 2/3. Therefore, probability of picking at least one vowel = 1-2/3=1/3.   ANSWER : 1/3
