What is the probability of choosing an even number out of seven counters?

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%

You ask a friend to think of a number between four and twelve what is the prbability it will be odd?
Assuming he has to pick a whole number his possible choices are 5, 6, 7, 8, 9, 10 and 11. Four of these seven possibilities are odd numbers so the probability of him choosing an odd number is 4/7.
What is the probability of getting an a from Alabama?
There are four a's in ALABAMA. The probability of choosing an a from a random draw of those seven letters is 4 in 7, or about 0.5714.If you are talking about getting a grade of A from a school in Alabama, that is entirely up to you and to how well you apply yourself.
What is the probability of rolling a seven on a pair of six-sided number cubes?
1/6 or 16.66.. %
What is the probability of drawing a seven of spades?
Probability of drawing a seven of spades, from a 52 card deck, is 1/52.
What is the probability of picking a seven or an eight?
What do you mean? LIke for example, if you have a bag with the follow: 888887777775 The probability would be 11/12 666778999999 The probability would be 1/4 (3/12) You take the number in total and that is your denominator(Number on bottom) You take the total number of sevens and eights and that is you numerator(Number on top) Than reduce as needed.
What is the probability of rolling a 7 with one roll of a standard number cube?
The probability of rolling a seven with one roll of a standard number cube is zero.

The probability that a number selected from random between 100 and 999 both inclusive will not contatin the digit 7?
For me I think it is conceptually easier to think about the probability that the number will contain the digit seven (and the probability that it does not contain the digit 7 is simply one minus the probability that it does). P(number will contain 7) = P(number is in the seven hundreds) + P(number is not in seven hundreds)*[P(number is in the X hundred seventies)+P(number is not in the X hundred seventies)*P(number ends in seven)] So essentially I am considering all of the numbers in the range that start with seven (i.e., are in the seven hundreds), then all of the numbers in the range that aren't in the seven hundreds but have a 7 in the tens place (i.e., the 170s, 270s, etc., and finally all the numbers that don't have a 7 in the hundred or tens place, but that end in 7). Plugging the numbers into my formula above, I get (100/900)+(800/900)*((10/100)+(90/100)(1/10)) = 7/25 is probability that the number does contain a 7, and 1-(7/25)=18/25 is probability that it does not.

How do you calculate experimental probability?
Experimental probability is the number of times some particular outcome occurred divided by the number of trials conducted. For instance, if you threw a coin ten times and got heads seven times, you could say that the experimental probability of heads was 0.7. Contrast this with theoretical probability, which is the (infinitely) long term probability that something will happen a certain way. The theoretical probability of throwing heads on a fair coin, for instance, is 0.5, but the experimental probability will only come close to that if you conduct a large number of trials.
How many probability of select seven number between 1 to 49 number?
using combination and permutation, it will come to 86 thousand times approximately
A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
Define the probability of something happening?
The probability that something will happen is the number of times that that something can occur divided by the number of times that anything can occur. An example would be to consider a standard deck of 52 cards. There are 4 sevens in the deck, so the probability of drawing a seven is 4 in 52, or 1 in 13, or about 0.0769.
