Question

A letter is selected at random from the English alphabet. What is the probability that the letter comes after D in the alphabet? 1 2 11 13 21 26 5 26

Answer 1

The answer is 11/13 because a through d cant be selected so its 26-4 which equals 24. This becomes 22/26 which can be simplified to the answer 11/13.

Answer 2

Answer:
`(11)/(13)`

Explanation:

The total number of letters in the English alphabet = 26

Since D comes at number 4 then,

The number of letters comes after D in the English alphabet =26-4=22

Now, the probability that the letter comes after D in the alphabet is given by :-

`P=\frac{\text{letters comes after D}}{\text{total letters}}\\\\\Rightarrow\ P=(22)/(26)\\\Rightarrow\ P=(11)/(13)`

Hence, the probability that the letter comes after D in the alphabet=
`(11)/(13)`
