A two-digit whole number is randomly selected What is the probability that it is an odd multiple of 3?
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
What is the probability of picking a number 6 from numbers one to 15 in 99 trials?
Prob(Pick 6 from 1-15 in 99 trials) = 1 - Prob(Don't pick 6 from 1-15 in 99 trials) = 1 - (14/15)99 = 1 - (0.933...)99 = 1 - 0.00108 approx = 0.9989
A number from 17 to 15 is drawn at random p an even number express the probability as a fraction?
That leaves 3 numbers, 15, 16, 17. If you're looking for the probability of drawing an even number it would be 1/3, or 0.333.
What is the probability of a prime number being picked randomly from the numbers 1 through 49?
There are 15 primes from 1 to 49 (including '1').The probability is (15/49) = 30.612 %(rounded)
What is the probability with 15 red pencils and 10 blue pencils of picking 1 red one?
60% chance or 15/25
What is theoretical probability of picking 2 squared numbers out of 15?
The answer depends on whether the first number is replaced before picking the second. If not, the probability is 0.029

What is the probability of picking odd numbers from 1 to 20?
Since there are 10 odd numbers (1, 3, 5, 7, 9, 11, 13, 15, 17, 19) in the 20 numbers (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the probability of picking an odd number in a random sample is 10 in 20, or 1 in 2, or 0.5.
What is the probability of a prime number being picked randomly from the numbers 1 - 15?
Prime numbers from 1 to 15 are: 2 3 5 7 11 and 13 So the probability is: 6/15 or as 2/5
Algebra 1 help with probability?
Probability is simple. Probability means the number of favorable outcomes over the total amount of outcomes.For example, if I had 15 marbles in a bag. 10 are yellow, and 5 are red. The probability of picking a yellow marble is 10/15, which simplifies to 2/3.
There is a bag of marbles 10 are red 15 are purple and 25 are yellow what is the probability of picking a purple marble?
3/10 or 0.3 is the probability of picking a purple marble.
What is the probability of picking 2 prime numbers chosen at random from a list of numbers 1 through 50 without replacement?
There are 15 primes through 50, so it would be: (15 * 14) / (50 * 49) = 3 / 35
What is the probability of a prime number being picked randomly from the numbers 1 -49?
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.
A two-digit whole number is randomly selected What is the probability that it is an odd multiple of 3?
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
What is the probability of picking a number 6 from numbers one to 15 in 99 trials?
Prob(Pick 6 from 1-15 in 99 trials) = 1 - Prob(Don't pick 6 from 1-15 in 99 trials) = 1 - (14/15)99 = 1 - (0.933...)99 = 1 - 0.00108 approx = 0.9989
A number from 17 to 15 is drawn at random p an even number express the probability as a fraction?
That leaves 3 numbers, 15, 16, 17. If you're looking for the probability of drawing an even number it would be 1/3, or 0.333.
What is the probability of a prime number being picked randomly from the numbers 1 through 49?
There are 15 primes from 1 to 49 (including '1').The probability is (15/49) = 30.612 %(rounded)
