There are infinitely many real numbers on the interval (1,10). There is therefore a probability of (1 / infinity) that the computer will pick 7, and this is a value that has a limit of zero. So the chances are zero that the computer will pick the number 7. Of course, the chances are also zero that the computer will pick any other number, which means that the computer can't pick a number at all, which means that the premises of the problem are somehow improper. I think the number being selected must be constrained to a maximum number of decimal places. The probability will then become finite.

about zero
in the interval (1,10) you have an infinity of real numbers. Ditto even in smaller intervals.
If your computer can work with any number of decimals, i.e. really "sees" an infinity of numbers between 1 and 10, then the probability of picking exactly 7.0000000 is zero.
In practice your computer can only cope with a given maximum number of decimals, in which case the probability of obtaining 7 will be very small, but not zero.
Now supposing you made a mistake, and meant an integer. Then the choices are 1,2,3,4,5,6,7,8,9,10, i.e. 10 possibilities. And the probability of picking 7 is 1/10th or 0.1.
Hope this helps

The answer is 1/infinity.
There are an infinite number of real numbers. So the chance that 7 is picked from an infinite group is 1/infinity.
For example, 1/2 is a real number, but so is 1/20 and 1/200 and so on...

The probability that this will happen if x is a real number tends to zero. tiny tiny small.

from 1 to 10 gives you 11 numbers, so
1/11 or 1 out of 11 or about .09%

1/10
because there's one seven out of ten possible choices.
But if you mean real numbers and not integers then the chances are incredibly small because there are infinite real numbers in that interval.

I yelled at a birdbath in my motor vehicle because i'm cool as like that. lol it sounds extraordinary and humorous, my beginning date is first november 1991 and that i'm donning black and white blouse with pink stripes on it.
