What is the probability that a randomly selected number between 1 to 100 both inclusive is divisible by either 2 or 5?

Exactly 20 of these numbers (5,10,15,…,100) are divisible by 5. Exactly 10 of these numbers (10,20,…,100) are divisible by both 2 and 5. Thus, 50 + 20 – 10 = 60 numbers are divisible by 2 or 5, and 40 out of 100 numbers are not. So the answer is 2/5.

What is the most random number between 1 and 10?

Exploited in carnivals, the fact that given a choice of any number between 1 and 10, people will most often choose 3 or 7. Humans are lousy random-number generators and an unusually large number of them will pick 37 while a smaller, but still lopsided number of people will pick 73.

What is the probability that a random chosen number from 1 to 12 is a divisible by12?

1/6
The probability that a randomly chosen number from one to twelve is a divisor of twelve is​ 1/6. 1/12.

Whats the most common number picked between 1 and 100?

Interestingly, every number between 1 and 100 was chosen by someone: the number 39 has fans, as does 53, 62 or any of the others. The lowest number not chosen by anyone was the number 110, and other numbers ending in 0 didn’t do well, either.

What is the probability of getting a prime number from the number started from 1 to 20?

Answer: The primes from 1 to 20 are 2, 3, 5, 7, 11, 13, 17, 19. There are 8 of them. So the probability of getting a prime number is 8/20 = 2/5.

What is the probability that you’ll choose 9 numbers out of 99?

Between 1 and 99 and 1 & 99 included there are 9 numbers which have a square since 10 square is 100. So the probability that you’ll chose these 9 numbers out of 99 is 9/99 or 1/11

How to pick a random number between any two numbers?

You can use this random number generator to pick a truly random number between any two numbers. For example, to get a random number between 1 and 10, including 10, enter 1 in the first field and 10 in the second, then press “Get Random Number”.

Where does the randomness in Your Number Generator come from?

The randomness in our number generator comes from physical processes – our server gathers environmental noise from device drivers and other sources into an entropy pool, from which random numbers are created [1].
