If a 4 digit number is chosen at random what is the probability that the product of the digits is 12?
49/9000
What is the probability of winning a lotter game where the winning number is made up of seven digits from 0 to 9 chosen at random?
1 in 4,782,969
Suppose a 10 digit positive integer leading digit not zero is chosen at random What is the probability that the digits in this integer are NOT distinct?
The answer is 9*9!/9*109 = 0.0003629 approx.
What is the probability of winning a lottery game where the winning numbers is made up of seven digits from 0 to 9 chosen at random?
It depends on how the game is structured, a piece of information that was not given in the answer... If the numbers are reused, then there are 1 x 107 (ten billion, in the short scale) permutations. Without combinations, then, the probability is 1 x 10-7. If the numbers are not reused, and we are playing combinatorial, in the style of most state sponsored lotteries, then the number of combinations is (10-3)! / 7!, which is 120, making the probability 1 in 120, or about 0.00833. There are other possibilities but, again, it depends on the rules, and you did not specify them completely.
How many 3 digit numbers are odd show working please?
The first (hundreds) digit can be chosen in any one of 9 ways from the digits {1,2,3,...,9}. With each one of these, the second (tens) digit can be chosen in any one of 10 ways from the digits {0,1,2,3,...,9}. With each of these combinationsm the third (units) digit can be chosen in one of 5 ways from the digits {1,3,5,7,9}. Altogether, then, there are 9*10*5 = 450 ways or 450 odd 3-digit numbers.
What is the probability of finding five numbers of six digits chosen randomly from 100000 to 999999?
There is 100% chance.
What is the probability of three digit numbers without repeated digits with numbers 0123456?
It is possible to create a 3-digit number, without repeated digits so the probability is 1.

If two dice are thrown what is the probability that some of digits is ten?
None of the digits can be 10, so the probability is 0.
You forgot the last 2 digits of your user ID for a games website You know that both digits are odd Find the probability that you type the correct last digits by randomly typing 2 odd number?

How many license plate combinations from 3 digits followed by 3 letters?
There are 26 different letters that can be chosen for each letter. There are 10 different numbers that can be chosen for each number. Since each of the numbers/digits that can be chosen for each of the six "spots" are independent events, we can multiply these combinations using the multiplicative rule of probability.combinations = (# of different digits) * (# of different digits) * (# of different digits) * (# of different letters) * (# of different letters) * (# of different letters) = 10 * 10 * 10 * 26 * 26 * 26 = 103 * 263 = 1000 * 17576 = 17,576,000 different combinations.
