Final answer:
The probability of picking either an s or a p from the letters of the word Mississippi is 6/11, which is considered likely but not certain.
Step-by-step explanation:
The student is asking about the probability of drawing either an s or a p from a set of cards each bearing a letter from the word Mississippi. To find the probability, we first count how many s's and p's are in Mississippi. There are 4 s's and 2 p's, a total of 6 cards that we are interested in. Since there are 11 letters in Mississippi, there are 11 cards in total. The probability of picking either an s or a p is therefore the number of s and p cards divided by the total number of cards, which is 6/11.
When it comes to the likelihood of this event, we can categorize it as likely but not certain, since there is more than a 50% chance but less than a 100% chance of drawing either an s or a p.
