MATHEMATICS.

There are 12 letters in the word MATHEMATICS.

The probability of selecting any one letter from the word MATHEMATICS is 1/12.

To calculate the probability of selecting a particular letter, we need to count the number of times that letter appears in the word and divide by the total number of letters.

For example, the letter "A" appears twice in the word MATHEMATICS, so the probability of selecting "A" is:

2/12 = 1/6

Similarly, the letter "M" appears twice, so the probability of selecting "M" is also 1/6.

The letter "E" appears three times, so the probability of selecting "E" is:

3/12 = 1/4

And so on for each letter in the word.
