To determine which set of letters from the word "MISSISSIPPI" has equal chances to be selected, let's first examine the frequency of each letter in the word:
- M: 1
- I: 5
- S: 4
- P: 2
Now, we can analyze the options:
- M and P: M (1) is less frequent than P (2).
- S and I: S (4) is less frequent than I (5).
- M and I: Again, M (1) is less frequent than I (5).
- M, I, and P: Frequencies are not equal (M=1, I=5, P=2).
For a pair of letters to have equal chances of being selected, they need to have the same frequency. Since no two letters among M, I, S, and P have equal frequencies, the correct answer would be:
None of the provided sets of letters (M and P, S and I, M and I) have equal chances to be selected.
If you have to choose one based on provided options, none fit the criteria of having equal chance due to different frequencies. However, if you want to answer the question as it is posed, none of the responses is correct.
