To determine which set of letters has equal chances to be selected from the word "MISSISSIPPI", we need to look at the frequency of each letter in the word:
- M: 1
- I: 5
- S: 4
- P: 2
Now, let's evaluate the options:
- S and I - Not equal chances (S appears 4 times, I appears 5 times).
- M, I, and P - Not equal chances (M appears 1 time, I appears 5 times, P appears 2 times).
- M and P - Not equal chances (M appears 1 time, P appears 2 times).
- M and I - Not equal chances (M appears 1 time, I appears 5 times).
None of the provided options have equal chances. However, the closest option based on individual letter frequency would technically be M and P, as they are the only two letters that can be compared directly, although they still do not have equal chances.
If forced to select an option from the provided choices, I would suggest M and P, as they are from the same pool of letters and provide the most even comparison in terms of frequency visibility (even though they are not equal).
