Question 4

Mathematics Permutation and Combination Medium

The number of different license plates that can be formed in the format 3 English letters ( \(A \ldots . . Z\) ) followed by 4 digits \((0,1, \ldots 9)\) with repetitions allowed in letters and digits is equal to

(A) \(26^{3} \times 10^{4}\)
(B) \(26^{3}+10^{4}\)
(C) 36
(D) \(26^{3}\)
View Dynamic Solution & Explanation
Correct Solution: Option A

Step-by-step Solution:

Quick Explanation:

Each of the 3 letters can be any of the 26 English alphabets: \(26^3\)
Each of the 4 digits can be any from 0–9: \(10^4\)
Since repetition is allowed, multiply the two: \[ \text{Total} = 26^3 \times 10^4 \]
