Using the letters in the state arkansas find the probability of picking an s and then an a without replacement

Start from the beginning by just rearranging the letters.

AAARKNSS

There are 8 letters.

'S' appears twice, so we have 2/8, or 25% probability.

AAARKNS

Now there are 7 letters to choose from.

'A' appears 3 times, so we have 3/7 or 43%.

Next, we multiply .43 (43%) by .25 (25%) to get our answer.  That should come out to 0.1075, or 11%.  11% is your answer.

Hope this helps!
