Answer:
48%
Step-by-step explanation:
We have 3 people and 5 floors
We can't have two or more people leaving in the same floor.
So, the first person to leave has 5 possibilities (all 5 floors)
Then, the second person will have only 4 possibilities, as this person can't leave in the same floor as the first one.
Lastly, the third person will have only 3 options (the 3 remaining floors that weren't selected).
The total number of possible choices, without restrictions, is 5 possibilities for each person, so 5*5*5 = 125 combinations
The combinations we want is 5*4*3 = 60 combinations
So the probability of all people choosing different floors is 60/125 = 0.48 = 48%
Answer:
You got it wrong, its the first option
Step-by-step explanation:
Since its not asking for a consectuive EVEN or ODD integer its not
X + X+2 + X+4...
Instead its just the normal way
X + X+1 + X+2 + X+3....
SO thats the correct answer.
What is the median of these numbers 30, 29, 32, 25, 36, 20, 30, 26, 56, 45, 33, 34?

I believe the median is 31, since it is halfway between 30 and 31, the two closest numbers to the median.
Answer:
The common difference is -2, so the formula for the nth term is 12-2(n-1).
This can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12.
The 5th term is 14-10=4; the 6th is 14-12=2. And so on
