The probability of selecting a constant from an alphabet depends on the specific alphabet in question and the number of constants it contains. For example, in the English alphabet consisting of 26 letters, if we consider constants to be consonants (21 in total), the probability of selecting a consonant randomly would be 21/26. Thus, the probability can be calculated by dividing the number of constants by the total number of characters in the alphabet.
Until the letter is selected, it is a variable. Immediately after it is selected, the outcome is no longer a variable but a constant.
It is 21/26.
The probability is 0.
It is 3/4.
No. f is a letter of the Roman alphabet. It cannot be a probability density function.
The statement about the probability of selecting the letter 'z' from the alphabet being 126 is incorrect. The probability of selecting any one specific letter from the 26 letters of the English alphabet is 1/26, not 126. Therefore, the probability of selecting 'z' is approximately 0.0385, or about 3.85%.

It is 21/26.
The answer depends on what you are selecting from. If you are selecting months in which the equinoces occur, the probability is 0.5
The probability is 0.4231, approx.
The probability of selecting a red card is 26 in 52 or 1 in 2. The probability of selecting an even card is 20 in 52 or 5 in 13. The probability, therefore, of selecting a red even card is 1 in 2 times 5 in 13 or 5 in 26.
The probability is 0.
The probability is 21/26.
The probability is 2:7.
It is 3/4.
