If you roll two fair dice, a green one and a red one?
A= are the outcomes on the dice independent?
B= Find P(1 on green die and 2 on red die)
C= Find P(2 on green die and 1 on red die)
D= Find P(1 on green die and 2 on red die) or (2 on green die and 1 on red die)

A= yes
B= p(1)*(p2)=1/6*1/6=1/36
C= p(2)*(p1)=1/36
D= 1/36=1/18 I hope it helps !

$7x^2 + 21 = 0\\\\7x^2 = -21\\\\x^2 = -\frac{21}{7}\\\\x^2 = -3\\\\x = \sqrt{-3}\\\\\boxed{\bf{x = i\sqrt{3}}}\\\\\boxed{\bf{x=-i\sqrt{3}}}$
