What is the probability of 2 odd numbers drawn from 1 through10?

Order is not important, so this is a combination problem.
There are 5 odd numbers from 1 to 10.
n(E) = 5C2 = 5*4/2*1 = 10
n(S) = 10C2 = 10*9/2*1 = 45
P = n(E)/n(S) = 10/45 = 2/9

What is the probability of spinning the spinner and landing on an odd number?
The probability of spinning the spinner and landing on an odd number depends on the number of odd numbers on the spinner and the total number of numbers on the spinner. If there are 3 odd numbers on the spinner and a total of 6 numbers, then the probability of landing on an odd number is 3/6, which simplifies to 1/2 or 50%.
What is the probability of choosing an odd number?
If you have an equal amount of odd and even numbers in a determined sample space, the probability of choosing and odd number is 1/2 (.5).
8 dices are thrown probability of even numbers?
Since there are only odd & even numbers, the probability is 1/2 or 0.5.
What is the probabiliy of selecting odd or prime numbers from 1 to 50?
The probabiliy of selecting odd or prime numbers from 1 to 50. First find out the probability of selecting odd numbers : 25/50 is 1/2. Lets find out the probability of selecting prime numbers: 15 / 50 . so, total is 40/ 50 is 0.82.
What is the probability of rolling both doubles and two odd numbers?
The answer depends on how many dice you roll and how often. If you roll four dice once, the probability of getting a double AND two odd numbers is 264/1296 = 11/54
What is the probability that odd numbers are drawn from 1 to 100?
Thereare 50 odd numbers and 50 even numbers in that range, so the probability is 1 out of 2

Probability of getting an even product when rolled 2 dice?
I'm assuming you multiply the numbers rolled. Thus the rules of even and odd numbers come into play. The only way to get an odd product is to roll two odd numbers. The probability desired is 1 minus the probability of rolling two odd numbers. The odds of rolling an odd number is 1/2. Since the rolls are independent events, the odds of rolling two odd numbers is (1/2)2 = 1/4 So the probability of getting an even product is: 1 - 1/4 = 3/4
What is the probability of choosing odd number?
If you chose the number out of an equal numberof odd and even numbers then it would be 50% chance. Like if you chose an odd number out of the numbers from 1 to 100

What is the probability of rolling an odd number or an even number on a cube?
To answer this problem you first see how many even and odd numbers there are. There are 3 odd and 3 even. so the fraction for even and odd is 3/6 so then in simplified form it is 1/2. If they ask to express the probability as a decimal number it would be .5 or.50
What is the probability of rolling both doubles and two odd numbers?
The answer depends on how many dice you roll and how often. If you roll four dice once, the probability of getting a double AND two odd numbers is 264/1296 = 11/54
What is the probability that you pick an odd number at random from 75 to 100?
From 75 to 100 (inclusive), there are 26 numbers, and 13 of them are odd.The probability of picking an odd number is 13/26 = 50%.
You roll a dice once what is the probability that you roll a even number?
The probability is .5 since half the numbers are even and half are odd.
What is the probability of rolling a 12 sided die and it landing on a prime number or an odd number?
In probability questions, the word "or" means add. Assuming the numbers are 1-12, the prime numbers would be 1, 2, 3, 7, and 11. The odd numbers are 1, 3 , 5, 7, 9, and 11. You don't add duplicates when determining probability, so all your options for a prime number or an odd number are 1,2,3, 5, 7, 9, and 11. This means there are 7/12 that are prime or odd, or a probability of 0.5833.
