What is the probability of getting a prime number from 1 100?

(Thus the probability that a randomly chosen number from 1 to 100 is prime is 25/100 = 25%.)

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

Probability of an event =Number of favourable casesNumber of total cases, We get, probability of choosing a prime number from 1 to 20 =820=25. Therefore, we get the probability of choosing a prime number from 1 to 20 as 25or 0.4.

What is the probability of getting a prime number from 1 to 16?

From the given 16 numbers, the numbers that are prime numbers are 2,3,5,7,11,13. Hence, \[\dfrac{3}{8}\] is the probability that the number selected from the numbers \[1,2,3,4,5,..........,16\] is a prime number. So, the correct option is “option C”. So, the correct answer is “Option C”.

What is the probability of the event that a number is chosen from 1 to 50 is an odd number?

How to calculate a prime number?

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can't be a prime number. If you don't get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).
