A box contains red chips and green chips. A person selects two chips without replacement. If the probability of selecting a red chip and a green chip is 15/56, and the probability of selecting a red chip on the first draw is 3/8, find the probability of selecting a green chip on the second draw, given that the first chip selected was a red chip. Leave answer as a simplified fraction.

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

d. you cannot tell because there are no values shown.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
