The factors of 50 are 1, 2, 5, 10, 25 and 50.
The prime odd factors of 50 are 1, 2, and 5.
The probabiliy of selecting odd or prime numbers from 1 to 50. First find out the probability of selecting odd numbers : 25/50 is 1/2. Lets find out the probability of selecting prime numbers: 15 / 50 . so, total is 40/ 50 is 0.82.
49 of them. ' 2 ' is the only even prime number.
13 + 37
49
The odd prime numbers from 1 to 50 are 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
Chances of not getting odd or prime number from 1 to 50= Chances of getting an even composite number from 1 to 50= Number of even composite numbers from 1 to 50/Total numbers from 1 to 50 = 24/50 or 48%Chances of not getting odd or prime number from 1 to 50= Chances of getting an even composite number from 1 to 50= Number of even composite numbers from 1 to 50/Total numbers from 1 to 50 = 24/50 or 48%Chances of not getting odd or prime number from 1 to 50= Chances of getting an even composite number from 1 to 50= Number of even composite numbers from 1 to 50/Total numbers from 1 to 50 = 24/50 or 48%Chances of not getting odd or prime number from 1 to 50= Chances of getting an even composite number from 1 to 50= Number of even composite numbers from 1 to 50/Total numbers from 1 to 50 = 24/50 or 48%
2 is the only even prime number. All primes other than 2 are odd numbers.
47 and 3 43 and 7
odd numbers
All prime numbers are odd, exept of the first prime number 2.
There are more odd numbers than prime numbers.
The odd composite numbers between 50 and 60 are 51, 55, and 57. Because all the primes are odd except for 2 and adding two odd numbers will result in an even number, one of the two prime numbers must be 2, which when added to an odd number will result in an odd number. So, we subtract 2 from each of these numbers and check whether it is prime. 51 - 2 = 49, which is not prime. 55 - 2 = 53, which is prime. 57 - 2 = 55, which is not prime. Thus, the number is 55, which can be written as 2 + 53.
