1 Jamal writes the letters K-A-N-S-A-S on cards and then places the cards in a hat. What is the probability an N?
1/3
1/5
5/1****
6/1
=============================
Kansas has 6 letters
One of them is N
therefore 1/6
is 6/1 a typo? You do not have probabilities bigger than 1.
Montana has 7 letters
Two of them are n
therefore 2/7
Now get serious and try the rest.
