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.
The probability is 3 out of 10.
The prime numbers from 1-6 are 2, 3, 5 (1 is not prime). There are 3 prime numbers on a dice and 6 total. therefore the probability of rolling a prime is 3/6. The probability of getting a tails when flipping a coin is 1/2. Therefore you just multiply the two. 3/6 * 1/2 = 1/4
Prime numbers from 1 to 15 are: 2 3 5 7 11 and 13 So the probability is: 6/15 or as 2/5
On a standard die, 2:1 in favour. This would be correct if 1 and 2 are accepted as prime numbers, which is allowed by some mathematicians and theories though not by all. ---- Having worked it out myself, I believe there is actually an even probability: Prime numbers: * 2 * 3 * 5 Not-prime numbers: * 1 * 4 * 6
The three prime numbers on the cube are: 2 3 and 5 so the probability is 3/6 or 1/2 simplified
The probability is 3 out of 10.
The probability of getting two prime numbers when two numbers are selected at random and without replacement, from 1 to 10 is 2/15.
The probability is 8/20.
The probability of rolling two prime numbers on a standard pair of dice is 1 in 4, or 0.25. Take the probability of rolling a prime on one die, 3 in 6, or 1 in 2, or 0.5, and square it.
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
15/49ExplanationThere are 15 prime numbers between 1 and 49 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). If you randomly choose one natural number from the 49 numbers between 1 and 49 inclusive, there is a 15/49 probability that it will be prime.
The prime numbers from 1-6 are 2, 3, 5 (1 is not prime). There are 3 prime numbers on a dice and 6 total. therefore the probability of rolling a prime is 3/6. The probability of getting a tails when flipping a coin is 1/2. Therefore you just multiply the two. 3/6 * 1/2 = 1/4
Prime numbers from 1 to 15 are: 2 3 5 7 11 and 13 So the probability is: 6/15 or as 2/5

"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.
There are 8 out of 20 numbers that are prime, so 8/20, or 2/5.
The probability of a prime number in a random pick from the numbers 1-49 is 15 in 49, as there are 15 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43,and 47) in the range of 1 to 49.
