What is the probability to choose prime numbers from 1 to 9?
The prime numbers from one to nine are 2, 3, 5, and 7. There are nine numbers from one to nine. The probability is 4 (the number of prime numbers) over 9 (the total number of numbers). Therefore, the probability of choosing a prime number is 4/9 or about 44 percent.
Explain the probability of tossing a prime number when you toss the cube with numbers 1 through 6?
2, 3 and 5 are prime so P = 0.5
If you roll a die what is the probability of rolling a prime number?
"The probability of getting a prime number in a die is 4/6" Actually there are 3 prime numbers on a die. 2, 3, and 5 are all prime numbers. So this tells you that you have 3 chances it will be a prime number and 3 chances it will not be a prime number. So the probability of getting a prime number on a die would be 3/6 or 1/2.
A number is chosen at random from the first 20 positive whole numbers What is the probability that it is not a prime number?
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
Which is the probability that a 1-6 number cube lands on a prime number?
The three prime numbers on the cube are: 2 3 and 5 so the probability is 3/6 or 1/2 simplified
If a bag contains 20 chips labeled with the numbers 1 through 20 and one chip is selected at random. what is the probability that the chip has the number 17 on it?
The probability of selecting a 17 (or any number for that matter) is 1/20 or .05 or 5%.
What is the probability of selecting a prime number from 1 to 20?
There are eight prime numbers between 1 and 20.2, 3, 5, 7, 11, 13, 17, 19If you randomly choose in number then you have an 8 in 20 chance of selecting a prime.The probability is selecting a prime number is 8/20 or 0.4
What is the probability of getting tails and selecting a 3 if you toss a coin and randomly select a number?
There are infinitely many numbers and so the probability of the second event is 0. As a result the overall probability is 0.
What is the probability of selecting a composite number over a prime number?
This cannot be answered Until and Unless a certain set of numbers are given as Sample Space.
What is the probability of selecting an even number out of the whole numbers 1 through 12?
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected
What is the probability that a random selected number from 20 to 30 is divisible by 3 and then divisible by 12 after replacing first?
To find the probability of selecting a number from 20 to 30 that is divisible by 3, we first identify the numbers in that range: 21, 24, 27, and 30. There are four suitable candidates, so the probability of selecting one of them is 4 out of 11 (the total numbers from 20 to 30, inclusive). After replacing the selected number, we check which of these are divisible by 12. Among the numbers listed, only 24 is divisible by 12. Therefore, the probability of selecting a number divisible by 3 and then finding it divisible by 12 is 1 out of 11, which simplifies to approximately 0.0909 or 9.09%.
What is probability of selecting a rational number from set of real number?
Zero, since there are infinitely more irrational numbers than rational numbers. Note that "zero probability" is not the same as "impossible" in this case. For more details, see the Wikipedia article on "Almost surely".
What is the probability of selecting a odd number from number 1-25?
from 1-25 there are 25 numbers 1 3 5 7 9 11 13 15 17 19 21 23 25 = 13 numbers [2 4 6 8 10 12 14 16 18 20 22 24 = 12 numbers] so probability of selecting an odd number is 13 in 25 13:25
You selecting a number from the numbers 1-20. What is the probability the number you select is a factor of 20?
30% chance. First, find the factors of 20: {1,2,4,5,10,20} There are 6 factors, out of 20 possible numbers. 6/20 = .3 = 30%
What is the probability of selecting a prime number from a deck of cards?
16 in 52 chance.
A number is chosen 1 to 25 find the probabillity of selecting a number greater than 18?
Probability is ratio of the events you want over the total number of events. There are 7 numbers greater than 18 and you have 25 total options, so your probability is 7/25 or 28%.
What is the probability of getting a number greater then 5 on a spinner?
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
