Answer:
16/69
Step-by-step explanation:
It's a probability of 16 out of 169.
There are 13 letters in MASSACHUSETTS. 4 of the 13 are the letter S, so there is a 4 in 13 chance to draw an S. Since the first card is replaced, there is still a 4 in 13 chance of drawing another S.
So the combined probability is 4/13 x 4/13 = 16/169.
