There are 15 primes through 50, so it would be:
(15 * 14) / (50 * 49) = 3 / 35
It is 0.4
2, 3 and 5 are prime so P = 0.5
The probability of rolling a prime number on a standard 6-sided die is 3 in 6, or 0.5.The sample space is [1 2 3 4 5 6] and the result space is [2 3 5]. 3 divided by 6 is 0.5.
Well, honey, let me break it down for you. A standard number cube has 6 sides, with numbers 1 through 6. Out of those numbers, only 2, 3, and 5 are prime. So, the probability of rolling a prime number with one toss is 3 out of 6, which simplifies to a 50% chance. Good luck, darling!
1/2
If the only numbers to pick from are 1 through 8, how can you get a factor greater than 10?
The probability is 17C4 = 2380
It is 0.4
The probability that the sum of the numbers rolled is either even or a multiple of 5 is 11/18.
A spinner has the numbers 1 thru 9. What is the probability of P(less than 6)? Write the answer as a decimal.
There are 20 numbers from 20 through 39, and 4 of them are prime (23, 29, 31, 37), the probability is 4 in 20 or 0.20.
There are 15 primes from 1 to 49 (including '1').The probability is (15/49) = 30.612 %(rounded)
The probability that the spinner will land on six depends on how many numbers are on the spinner. If the spinner is only 1 through 6, then there is a 16.67% probability that the spinner will land on six with each spin.
Because it is the process of deriving probability through repeated experiments.
It is 0.375
2/3 or 66.667% chance
The simplest way to get a probability of zero is to have an impossible event. For example, with a die (that's the singular of "dice") that has the numbers 1-6, getting each of these numbers has a probability of 1/6; getting the number has a probability of 0.There is another way to get a probability of zero, which occurs for certain situations that involve infinity; if you are prepared to read through some somewhat intense math, check the Wikipedia article on "Almost surely" for more details. (In this case, "almost surely" means a probability of 1; while "almost never" means a probability of 0.)
