What is the probability of selecting a prime number from 1 to 50?

What is the probability of selecting a prime number from 1 to 50?

The probability that a prime is selected from 1 to 50 can be found in a similar way. The primes that are less than 50 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. There are 15 primes less than or equal to 50. Thus the probability that a prime is selected at random is 15/50 = 30\%.

What is the probability of getting a number divisible by 3?

Since numbers that are divisible by 3 appear quite regularly at every third number, and you are ending on a number divisible by three, the probability must be 1/3 or 33.33\%. 1, 2, 3, 4, 5, 6, 7, 8, 9……. 2992, 2993, 2994, 2995, 2996, 2997, 2998, 2999, 3000.

What is the probability of selecting a number from 1 to 10?

Favourable possibilities are: 1 or 3 or 5 or 7 or 9. (Total 5 possibilities). Therefore Probability = 5 / 10 = 1/2 or 50\%.

What probability is the factors of 36?

Solution: Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, and 36. Factors of 37 = 1 and 37. Hence, the common factor of 36 and 37 is 1, as 37 is a prime number.

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

from 1 to 50 we have a total of 50 numbers, therefore we have a total of 50 possible picks. As every other number is odd, then 25 out of the 50 numbers are odd. Then the probability is the number of desireable picks (here it is odd numbers) over the number of possible picks.

What is the probability of a number divisible by 2 and 3?

Required probability=n(A)n(S)=41155. Hope it helps. First of all, you have to calculate the probability of selecting a number and being divisible by 2 and 3. For that you have to count how many numbers are divisible by 2 and 3 between the first hundred numbers, I call it n2,3 and divide it by 100.

What is the probability of even that a number chosen from 1 to 10 is a prime number?

Main Answer : 2:5 is the probability of the event that a number chosen from 1 to 10 is a prime number…

What is the factor of 50?

The factors of 50 are the natural numbers that divide the original number, evenly. They are 1,2,5,10,25 and 50.

How many factors does 49 have?

3 factors
Solution: The factors of 49 are 1, 7, 49. Therefore, 49 has 3 factors.

What is the probability of a random number between 1-50?

=0.4 i.e., 40\% is the probability of a random number chosen between 1 and 50 could be multiple 4 or 5 One die is thrown twice. What is the probability of getting a 3?

How many numbers are divisible by 5 between 1 and 50?

There are 10 numbers divisible by 5 between 1 and 50 (5, 10, 15, 20, 25, 30, 35, 40, 45, 50). Therefore the probability of geting a myltiple of 5 = 10/50 = 1/5

What is the probability of selecting a factor of 36?

Probability of selecting a factor of 36 while selecting a number between 1 to 50 = No. Of favourable outcomes / No. Of total outcomes A integer is chosen from 1 to 50.

What is the required probability of winning the lottery?

Find the probability that it is a good screw. Hence the required probability is 9/10. 3. In a lottery, there are 5 prized tickets and 995 blank tickets. A person buys a lottery ticket. Find the probability of his winning a prize. Hence the required probability is 1/200.
