Mrrafil [7]

Answer:

Step-by-step explanation:

y=(2x²+x)³+(x-1)/(1-x)

=(2x²+x)³+(x-1)/-(x-1)

=(2x²+x)³-1

dy/dx=3(2x²+x)(4x+1)-0

=3x(2x+1)(4x+1)

Amaya and bo each roll a fair, ordinary six-sided die with the numbers $1,2,3,4,5,6$ on the sides. what is the probability that

pashok25 [27]

On the added picture is given a table of all possible die rolls, for example, under a pair (2,3) you mean that Bo rolls 2 on a die and Amaya rolls 3.

All red shaded cells responds to those choices, when Amaya rolls more than Bo.

Let's count: all possible rolls make up 36 choices and red shaded rolls make up 15 choices, then the probabiliry is

$\dfrac{15}{36} = \dfrac{5}{12}$ .

Answer: $\dfrac{5}{12}$ .
