The probability that either the score on the green die is 1, or the score on the red die is 6 is 1/6.
<h3>What is the probability?</h3>
Probability determines the odds hat an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability = [[(number of green die / total number of die) x (number of sides that have a score of 1 / total number of sides) ]+ [[(number of red die / total number of die) x (number of sides that have a score of 6 / total number of sides) ]
[(1/2) x (1/6) + [(1/2) x (1/6)]
= 1/12 + 1/12 = 2/12 = 1/6

ANSWER
EXPLANATION
The given parabola has equation of the form
where (h,k) is the vertex of the parabola.
The vertex of the given parabola is (4,-2).
and p is the distance between the foci and the vertex.
The parabola opens towards the positive x-axis, therefore p=2.
Hence the equation of the parabola is
