Answer:

x = ± \frac{2}{3}

Step-by-step explanation:

9x² - 4 = 0 ( add 4 to both sides )

9x² = 4 ( divide both sides by 9 )

x² = \frac{4}{9} ( take the square root of both sides )

x = ± \sqrt{\frac{4}{9} } = ± \frac{\sqrt{4} }{\sqrt{9} } = ± \frac{2}{3}

P (Blue) = 0.3667

P (Large / Blue ) = 0.2727
