The probability depends on the range of numbers from which to choose.
If there is no limit to the range then probability is incalculable.
probability is a guess and actuality is what will happen
1. subjective probability (intelligent guess) 2. relative frequency (in percent) 3. classical probability (in decimal)
Both are equivalent! * Probability of using 50-50 and getting the right answer: 1/2 * Probability of using double dip and getting the right answer: = Probability that either first or the second guess is correct P(First guess is correct) = 1/4 + P(First guess in wrong and second guess is correct) = 3/4 * 1/3 = 1/4 = 1/2
Oh, dude, the probability of guessing the last digit of a phone number is 1 in 10, because there are 10 possible digits (0-9). So, like, if you randomly guess, you have a 10% chance of getting it right. But hey, don't stress about it too much, it's just a phone number!

idk i'm only in 5th grade my guess would be 3
Objective probability is based on some basis of fact, experimentation, or analysis. Subjective probability is based on someones guess.
Since blue is the only color named, I'd guess that the probability is 100%.

That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.
in probability, you only guess. while in graphs you only draw lines. but both are boring.
empirical probability is when you actually experiment with it and get data values, and theoretical probability is when you use math to make an educated guess.
The probability of guessing a 4-digit numerical code is 1:10000. If the code can contains numbers AND letters - that figure rises to 1:1,679,616
Assuming that you cannot repeat any of the numbers that you are using to guess (e.g., would not guess 1, 4 and 4) AND that a match only counts once (e.g., in the serial number A23345678D, the matching 3 only counts as a single match despite appearing more than one time), the probability is between 15.4% and 15.5% (via 5MM simulations). If we loosen the rules and say that there can be double matches with the numbers that you are guessing (e.g., in the serial number above, if 3 was a guess number, there would be two matches, not just one), the probability is between 25.4% and 25.5% (via 5MM simulations) The spirit of the question suggests that we would never repeat a guessed number.
There is not one. In statistics, if the number of possibilities and desired outcomes does not decrease, the probability stays the same with each trial. Meaning that each guess would be the same probability as the previous guess. Now if your looking at guessing something that can have a limited number of correct guesses, like whether I'm typing this answer on a Windows, Mac or Linux machine, each guess eliminates a possible answer. So the odds would be better if you guessed Mac and then I said you were wrong and you guessed again.
So I guess the counters are numbered 1 through 7, and you pick one of them. There are 7 possibilities, 3 of them are even numbers {2,4,6}, so the probability is 3 out of 7. 3/7 = approx. 42.86%
