<span>The probability none comes from C. is (30/80)*(29/79)*(28/78)=0.0494.
The three buttons have to be pressed in a certain order. Because three buttons have all been pressed many times, then the buttons will be assumed to be distinct.
The chances are then 3! or 6, and the probability is (1/6)

In this instance, there are 10 ways to choose each button, three times, independent, since the buttons don't have to be distinct. This is 10^3 or 1000, and the probability is (1/1000).</span>
1st number = x, 2nd number = y
Translating the question mathematically it becomes:
x-2 = 3y, or to make it easier: x= 3y+2, x+y= 22
Thus:
(3y + 2) + y = 22
4y + 2 = 22
Move the 2 on the other side, changing its sign to negative:
4y = 22 - 2
4y = 20
Divide by 4, to obtain only y:
4y : 4 = 20 : 4
y = 5
To obtain x:
x= (3*5) + 2= 15+2 = 17
Verify it: 17+5=22
Answer: 4
Step-by-step explanation:
When we roll a 6-sided dis , the total possible of outcomes : 1, 2, 3, 4, 5, 6
Thus , the total number of outcomes =6
The favorable outcomes: 2, 1, 3 , 5
Thus , the number of favorable outcomes = 4

Answer:
well E is (-7,-7) F is (-2,-3) G is (-1,-6)
Step-by-step explanation:
A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.
An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.
