A bag has six balls labeled A, B, C, D, E, and F. One ball will be randomly picked, and its letter will be recorded as the outcome. Give the sample space describing all possible outcomes . Then give all of the outcomes for the event of choosing the letter B, C, or E. If there is more than one element in the set, separate them with commas .

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
