If a number is chosen at random from the numbers 1 to 20 inclusive what is the probability that an even number will be picked?
There are 20 numbers in total from 1 to 20. The even numbers in this range are 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20, totaling 10 even numbers. Therefore, the probability of picking an even number is the number of even numbers divided by the total numbers, which is ( \frac{10}{20} = \frac{1}{2} ). Thus, the probability of selecting an even number is 0.5 or 50%.
What is the probability of picking up number 15 from 1 to 20 numbers?
The probability, in a single random selection, is 1/20 or 0.05
What is the probability of picking an s from HOUSE?

What are the odds of picking 6 numbers out of a possible 20?
The odds of picking 6 numbers out of a possible 20 can be calculated using combinations. Specifically, the formula for combinations is ( C(n, k) = \frac{n!}{k!(n-k)!} ), where ( n ) is the total number of options (20), and ( k ) is the number of selections (6). This results in ( C(20, 6) = 38,760 ) possible combinations. Therefore, the odds of picking a specific set of 6 numbers correctly from 20 is 1 in 38,760.
In a bag of marbles you have three green two yellow six blue and nine red marbles. What is the probability of picking a red marble from the bag?
To find the probability of picking a red marble, first determine the total number of marbles in the bag, which is 3 (green) + 2 (yellow) + 6 (blue) + 9 (red) = 20 marbles. The number of red marbles is 9. Therefore, the probability of picking a red marble is the number of red marbles divided by the total number of marbles, which is 9/20 or 0.45.
What is the probability of picking 3 from 20 in fraction form?
The probability of picking a distinct set of 3 numbers from 20 is1/[20!/(3!)(17!)]= 1/1140The probability of only picking 3 from 20 is1/20

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 that your friend will pick a 15 or a 16 from 1 to 20?
