You pick 6 digits (0-9) at random without replacement, and write them in the order picked. what is the probability that you have written the first 6 digits of your phone number? assume there are no repeats of digits in your phone number.

1/151200

Step-by-step explanation:

The number of ways to pick an exact order of any 6 different numbers from 10

=

= 10×9×8×7×6×5 = 151200 ways

which means the first one can be any of 10 numbers

The second one can be any of 9 numbers

The 3rd one can be any of 8 numbers and so on

Now the 6th one can be any of 5 numbers

Thus there are  10×9×8×7×6×5 = 151200 ways  to choose the number

so the required probability is 1/151200

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

ask the math teacher she or he would know lol.
