To find the probability of not selecting a multiple of 2 or a multiple of 3 from the numbers 1 to 10, we first identify the multiples: the multiples of 2 are 2, 4, 6, 8, 10, and the multiples of 3 are 3, 6, 9. The multiples of either 2 or 3 are 2, 3, 4, 6, 8, 9, and 10, totaling 7 numbers. This leaves us with 1, 5, and 7 as the numbers that are neither, giving us 3 favorable outcomes. Therefore, the probability is 3 out of 10, or 0.3.
A multiple of 6 because you can get a 6 and 6, a 1 and 5, a 2 and 4, and a 3 and 3. The only factors you can get are 2, 3, and 6.
A common multiple
Probability equals the number of ways an event can occur divided by the total number of events. The total number of events is (b=boy, g=girl) is bb, bg, gb, gg. The probability is then 1/4.
properties of probability
No number between 61 and 107 is a multiple of 41020. A multiple is a number that another number can divide into. The lowest multiple of any number is itself. You may have meant factors, which is a number that divides into a multiple of itself. In that case there is a factor of 41020 between 61 and 107. That number is 70.
It is 0.02

Probability is ratio of the events you want over the total number of events. There are 7 numbers greater than 18 and you have 25 total options, so your probability is 7/25 or 28%.
50 50 odd or even same probability
16 in 52 chance.
It is 0.4
The odds of two people selecting the same number out of 1000 can be calculated as follows: each person has 1000 options, and for the second person to match the first, there is only 1 favorable outcome (the number chosen by the first person). Therefore, the probability of both selecting the same number is 1 out of 1000, or 0.1%. This means the odds are 1 in 1000.
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
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.
In the range of 1 to 10, there are five odd numbers: 1, 3, 5, 7, and 9. Since there are a total of 10 numbers, the probability of selecting an odd number is the number of odd outcomes divided by the total outcomes. This gives us a probability of 5/10, which simplifies to 1/2 or 50%.
1 out of 20 this is because there are 20 numbers in total, and there is only one 7 in there. (Assuming that there is the same probability for each number to be chosen, and that 17 is excluded as an affirmative outcome)
There are infinitely many numbers and so the probability of the second event is 0. As a result the overall probability is 0.
