Question

A letter of the English alphabet is chosen at random
calculate the pro bobility that the letter so chosen
precedes K
and is
a vowel .​

Answer 1

Answer:i) 5/26    ii) 3/26   iii) 2/26 = 1/13

Step-by-step explanation:

i) Let the probability of getting a vowel be A

A = { a,e,i,o,u} ; n(A) = 5

n(S) = 26

P(A) = n(A)/ n(S)

      = 5/26

ii) Let the probability of getting a letter preceding m and is a vowel be B

B = { a,e,i } ; n(B) = 3

n(S) = 26

P(B) = n(B)/ n(S)

      = 3/26

iii) let the probability of getting a letter that follows m and is a vowel be C

C = {o,u} ; n(C) = 2

n(S) = 26

P(C) = n(C)/ n(S)

      = 2/26

      = 1/13

Answer 2

Answer:

here's ur answer ✌️✌️

total number of letters = 26

number of letter preceding k =15

therefore probability =15/26

total number of letters =26

number of vowels =5

therefore probability = 5/26
