A number cube numbered 1-6 is rolled once. What is the probability that the side facing up shows a 4

it will be one out six to roll a four

Step-by-step explanation:

there is one being rolled to be a 4 out of six

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

it should be a and d. lmk if i'm wrong xd
