Question 3551 – UGC NET CS 2016 Aug- paper-2

What is the probability that a randomly selected bit string of length 10 is a palindrome?

Correct Answer: B

Question 4 Explanation: 
Palindrome is a number that remains the same when its digits are reversed.
Ex: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121…,
Step-1:​ Here, string length is 10. If we consider first 5 numbers as random choices like 0 or 1.
Remaining 5 numbers are fixed. Total number of possibilities are 2​ 10​ . But we are only considering first 5 choices. The probability is 2​ 5​ .
Step-2:​ The probability 2​ 5​ /2​ 10
= 1/2​ 5
= 1/32
A
1/64
B
1/32
C
1/8
D
1⁄4
