To determine which set of letters has equal chances of being selected from the word "MISSISSIPPI", we need to count the occurrences of each letter:
- M: 1 time
- I: 5 times
- S: 4 times
- P: 2 times
Now, examining each pair:
- M and I: Not equal (M = 1, I = 5)
- S and I: Not equal (S = 4, I = 5)
- M and P: Not equal (M = 1, P = 2)
- M, I, and P: Not equal (M = 1, I = 5, P = 2)
None of these pairs or groups have equal chances of being selected since they all have different frequencies.
However, if we are looking for any pair from the options provided that has the same probability of being selected, it turns out that none work since they all have differing counts.
Thus, the conclusion is that no set listed has equal chances for selection from the word "MISSISSIPPI".
