Step  1  :Pulling out like terms :

 1.1     Pull out like factors :

   2p + 8  =   2 • (p + 4) 

Equation at the end of step  1  : Step  2  :Equations which are never true :

 2.1      Solve :    2   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 2.2      Solve  :    p+4 = 0 

 
Subtract  4  from both sides of the equation : 
 
                     p = -4

One solution was found :                   p = -4

Lydia tosses two six-sided number cubes.A) List the sample space.
B) What is the probability of Lydia rolling pairs of the same number?
C) What is the probability that at least one number will be a 3?

Answers

b) The probability of Lydia rolling pairs of the same number is 1/6.

c) The probability that at least one number will be a 3 is 11/36

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

a) The Sample Space is

(1, 1)       (1, 2)   (1, 3)        (1, 4)         (1, 5)         (1, 6)

(2, 1)     (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

(3, 1)     (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)

(4, 1)     (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

(5, 1)     (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)

(6, 1)     (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)

b) The probability of Lydia rolling pairs of the same number

= 6/36

= 1/6

c) The probability that at least one number will be a 3

= 11/36
