1/6 probability

Step-by-step explanation:

because probability of s in these letters is 1/6 so it will be 1/6

Answer 2

Answer:

Step-by-step explanation:

There are 6 letters in total.

U need 2 letter words with S as one letter.

No repetition.

__ __=> First position can be S, then the second position can be remaining 5 letters. Similarly, first position can be any of the other 5 letters, and second can be S. So total of 1*5 + 5*1 words. => 10 2-letter-words with S.

Now in total you can form 6*5 words without repetition.

So probability of a 2-letter-word with S= 10/30

=>10/30 => 1/3
