>>14357925>>14357978>>14358005Lets take this question in parts.
What are the chances that an arbitrary two letters in the alphabet spell HI.
The chance that one is H is 1/26 and the chances that the next is I is 1/25.
So the chances of both is 1/(26*25).
Then we ask how many slots can this pair of numbers fit and be next to one another in that order.
There are 26 possible positions but the final position would put I back at the beginning of the alphabet and we would say that's not HI.
So there are 25 places this could happen.
25 chances at a 1/(26*25) event would be 1/26 total chance of this happening.
>>14357880OP if this is your fucking homework I'm severely disappoint.
