Answer»

Total letters = 26

1) Total consonant = 21Probability of choosen letter is consonant = 21/26

2) All alphabets except vowels are consonant.So, probability of choosen both alphabet and consonant is 0.

3) Number of letters before Mare 12Probability of choosen letter before M = 12/26 = 6/13

4) Number of vowel = 5Probability of choosen not a vowel = 1 - 5/26 = 21/26
