each of the letters in the word SAMSUNG are on separate cards, face down on the table. If you pick a card at random, what is the probability that it's letter will be S or U
There are 7 cards. The number of possible correct picks is 2 (if you pick an 'S') plus 1 (if you pick the 'U') = 3 ways to succeed. So the probability of success is 3/7 ... about 43% .
