set # 1 = { a , b , c , d , 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 ?
so not a vowel in set - 1 : 3 / 5 and not a vowel in ser - 2 : 5 / 6 now , 3 / 5 ∗ 5 / 6 = 12 this is for not a vowel . then for at least one vowel will be = 1 − 1 / 2 = 1 / 2 answer will be c .
multiply(divide(const_3, add(const_3, 2)), divide(add(const_3, 2), add(add(const_3, 2), 1)))
