The list of prime numbers that are less than 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47. We can see that there are 15 prime numbers less than or equal to 50. Thus the probability of randomly choosing one prime number from 1 to 50 is 15/50 = 3/10 = 0.3.
What is favorite number?
A survey launched by a British mathematics writer has found that seven is the world’s favorite number, reports The Guardian. The results of the online survey were published on Tuesday, with three, eight and and four coming second, third and fourth. Of course it’s the world’s favorite number,” he said.
How do you pick a random number between 1 and 10 in python?
The randint() function of the random module returns a random number between two given numbers. To get a random number between 1 and 10, pass 1 and 10 as the first and second arguments, respectively.
What is the command for random number from 1 to 10?
If you want to generate random numbers from 0 to 10, you multiply the random number by 10. If you want to generate N random numbers from A to B, use the following formula: A + (B-A)*rand(1,N); “(B-A)” makes the difference between the lowest and highest random number the same as the difference between A and B.
How many tries to guess a number between 1 and 100?
(Note that, if you allow guesses at ranges, the answer is different. You can, by carefully selecting your ranges, go from 100 to 34 at worst (by stating “the number is between 34 and 67”) on your first go. Second gets you down to 12. Then 4, then 2, then 1.
How many guesses in a range of 7?
Whether you are high or low, you will have a range of 7 left. Let’s say you were low, so the range is now 9 to 15. Guess 12 and you will have 3 left either way. Now guess 10 or 14 for your third guess and you will get it on the fourth try.
What is the probability of guessing a number between 1 and 100?
The answer is that 2 7 = 128 > 100. Say that you start by guessing 50. Either you’re right, in which case you’re done, or you’re wrong; if you’re wrong, then you know that the number is either in [ 1, 49] or [ 51, 100], so that there are only 49 or 50 possibilities left.
How many guesses can you make to pick a number?
Each guess eliminates one number as well as dividing the remaining numbers into 2. One guess can pick a number from 3 (is your number 2?). 2 guesses can do 7. N guesses can pick a number from 2 N + 1 − 1, so 6 guesses can do it for 1-127.
