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%

-1/2 +2

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
