Total letters ;= 26 [A, B, C ….. Z]
Probability = \(\frac {No.\,of\, favourables}{Total\, No.\,of\,outcomes}\)
a) Vowels = a, e, i, o, u [5]
∴ (vowels) = 5/26
b) Letter after P = 10
[Q, R, S, T, U, V, W, X, Y, Z]
Probability of a letter that comes after
’P’ = 10/26 = 5/13
c) A vowel or a consonant
Vowel or consonants = 26
[all letters from A to Z]
P(vowel or consonant) = 26/26 =1
d) Not a vowel = 21
[other than A, E, I, O, U]
∴ P(not a vowel) = 21/26
