When you are determining The probability of an event why must the probability be between 0 and 1
slega [8]

The probability of an event cannot be less than 0 because 0 means it's impossible. The probability of an event cannot be more than 1 because 1 means that it's certain that it will happen. That's why the probability must be between 0 and 1.

Can somebody explain slope to me with the formula and with the graph
slavikrds [6]

Answer:

Step-by-step explanation:

The slope formula is M=y2-y1

                                   ______

                                        X2-X1

Ex. (-1,1) and (1,-2)

      x1,y1       x2,y2

-2+1        -3

_____= ____  

1+(+1)        2

Graph:

Any linear function can be quickly graphed using the form: y=mx+b

X: independent variable

y: dependent variable

M: slope

b: y-intercept

(When you don't have a denominator for M put a 1 Ex. 4--> 4/1)  

Ex. y=-1/2x + 4

M= 1/2

B: 4

Rise/Run = -1/2     "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
