Probability =
(number of ways to succeed) / (total possible outcomes) .
There are 6 total possible outcomes of rolling one honest die.
Only one of them is a ' 4 '.
-- So the probability of rolling a '4' on the first roll is 1/6 .
-- The probability of rolling a '4' on the second roll is 1/6 .
-- The probability of BOTH events is
(1/6) x (1/6) = 1/36 = (2 and 7/9) percent .
Answer:
its 126
Step-by-step explanation:
For this case we have the following expression:
6 * 1 = 6
We observe that we have two numbers that multiplied give as a result the value of one of the numbers.
The name of this property is called identity property.
In matrices there is also the identity matrix. It is a matrix whose diagonal is formed by the number one.
Answer:
A property that is illustrated by 6 * 1 = 6 is:
identity
Answer:
x = -7
How to:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
5°x-(2°x-9)=0
Pull out like factors:
21 + 3x = 3 • (x + 7)
Equations which are never true: Solve 3 = 0
<em>Solving a Single Variable Equation:</em>
Solve : x+7 = 0
Subtract 7 from both sides of the equation : x = -7
