Each letter of the alphabet is printed on an index card. what is the theoretical probability of randomly choosing any letter except z? write your answer as a fraction or percent rounded to the nearest tenth.
the theoretical probability of choosing a letter other than z is

The theoretical probability of choosing a letter other than Z is 96.2%

We know that there are 26 alphabets.

Also, the number of  alphabets which are other than Z are: 25

Now we are asked to find the theoretical probability of randomly choosing any letter except Z :

It is the ratio of the number of alphabets other than Z to the total number of alphabets.

which is calculated as:

In percent to the nearest tenth the theoretical probability is given by:

                    96.2%

how many players are there?

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
