Letters tiles, H, O, N, E, SNT are shuffled and placed in a box. A letter is selected at random what is the probability of selecting A would the answer be one over six or one or zero or six over zero

The answer would be zero. This is because the letter "A" is not one of the letters in the set {H, O, N, E, S, T}. Therefore, the probability of selecting the letter "A" from the set is zero.
