It is best to assume independence between the numbers (i.e. the 4th doesn't affect the 5th)
If that is true, then the odds are .1
(We don't have to worry about area codes exist, or about avoiding 911, since this is the 4th digit)
That depends what rules you use, to choose a number randomly.
There are a number of asymptotic distributions developed by various mathematicians. A simple one to sues is that, given an integer N, the probability that a random positive integer which is not greater than N is prime is very close to 1 / ln(N) where ln(N) is the natural logarithm of N..
Given any random digit, there is a 10% probability that the next digit is the same. That is, the probability of the previous number repeating is 10%. Whether this constitutes often (as suggested by the question) or not is a matter of opinion.
The probability, in a single random selection, is 1/20 or 0.05
For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.

Assuming that the tiles spell ALGEBRA, the probability is1/7*4/7 = 4/49
infinite
The probability is 0.
Type your answer here... The sentence PROBABILITY IS FASCINATING is spelled out with Scrabble® tiles. The tiles are then scrambled and put into a box. You choose one at random. What is the probability that you'll draw out the letter A?
It is a variable that can take a number of different values. The probability that it takes a value in any given range is determined by a random process and the value of that probability is given by the probability distribution function.It is a variable that can take a number of different values.
