What is the probability that the randomly displayed time is a palindrome?
That depends on how many digits. If it is a one digit number, it has 100\% chance to be a palindrome. If it is a two digit number, there are 90 two digit numbers (10 to 99) and 9 of them are palindromes (11, 22, 33 etc.) so there is a 10\% chance of it being a palindrome.
What is the probability that a two digit number selected at random is multiple of 3 and not a multiple of 5?
Probability that a two-digit number is a multiple of 3 and not a multiple of 5 = 30-6 = 2490= 415. Find the probability that a number selected at random from the numbers 1, 2, 3., 34 , 35 is (a) a prime number, (b) a multiple of 7, (c) a multiple of 3 or 5.
Does palindromic mean?
: a word, phrase, sentence, or number that reads the same backward or forward “Step on no pets” is a palindrome.
What is the probability that the word is palindrome?
So the probability of your word being a palindrome is 1/263.
What is the probability that a randomly selected bit string of length 10 is a palindrome?
What is the probability that a randomly selected bit string of length 10 is a palindrome? i.e. 25 choices for first half and 25 choices for second half. Probability = favorable outcome / total outcome = 25/ 210 = 1 / 25 = 1 / 32.
How do you find the palindrome of a number?
The algorithm follows 3 steps:
- Declare two variables: one stores the given number, and the other stores the reversed number.
- Run the do-while loop until the number of digits in the reversed number are equal to the number of digits in the given number.
- Check if the reversed number is equal to the given number.
Why do I see palindrome numbers?
A palindromic number is the same forward and backward, such as 12321. The first thought I get is “you’ve done something and now must undo it in reverse,” such as the 12 steps in AA where you make amends to those you have hurt. That such a number continues to appear means you haven’t dealt with the situation yet.
What is the probability that an n digit number is palindrome?
So the probability that an N digit number is palindrome is 10ceil ( N / 2 ) / 10N or 1 / 10floor ( N / 2 ) Below is the implementation of the approach: // This code is contributed by divyeshrabadiya07. Attention reader!
How many 3 digit numbers are divisible by 5?
Hence total number of 3 digit numbers which are divisible by 5 is 9 × 10 × 2 = 180. However total number of 3 -digit numbers is 900. Thanks for contributing an answer to Mathematics Stack Exchange!
How many leading zeros are allowed in a n digit number?
As leading zeroes are allowed total number of N digit number is 10N. A number is a palindrome when first N/2 digits match with last N/2 digits in reverse order. For even number of digits, we can pick first N/2 digits and then duplicate them to form the rest of N/2 digits so we can choose (N)/2 digits.
