Four 6-sided dice are rolled. The dice are fair, so each one has equal probability of producing a value in 1, 2, 3, 4, 5, 6 . Let X = the minimum of the four values rolled. (It is fine if more than one of the dice has the minimal value.). What is P (X ≥ k) as a function of k?

i believe the answer is d.

hope it you! : d

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
