The directrix is x=-2, which means the parabola opens horizontally instead of vertically. The equation is (y - k)²<span> = 4p (x - h), where the </span>focus<span> is (h + p, k) and the </span>directrix<span> is x = h - p
in this case, h+p=2, k=0, and h-p=-2
solve for h and p: h=0, p=2
plug the numbers into the equation: (y-0)</span>²=4*2(x-0)
simplify: y²=8x
The probability that both marbles chosen from the bag will be yellow is 3/14.
<h3>What is the probability?</h3>
Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that both marbles chosen from the bag will be yellow = (number of yellow marbles / total number of marbles) x (number of yellow marbles - 1/ total number of marbles - 1)
4/8 x 3/7 = 3/14
