Each of the students in a particular class writes down a letter of her choice on a piece of paper and folds the paper to put it into a bowl. All the chosen letters are shown below.
Alex chooses a letter from the bowl randomly. What is the probability that Alex picks a paper with the first letter of his name written on it? After replacing the chosen paper with ‘A' in the bowl, he picks a letter again. What is the probability of picking the letter ‘S'?
