Of all the different permutations of the letters in the word STOP, if you choose one at random, what is the probability that it will start with the letter P?
(the answer is a fraction)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The graph isn’t that clear

C, e, and a (hope it )
