Answer:
a) 2/5
b) 1/10
Step-by-step explanation:
There are 20 people total.
a is that the chosen child is a girl.
2 + 6 = 8, --> there are 8 girls --> simplify
8/20 = 4/10 = 2/5
b is the probability that the chosen child is a left-handed girl, --> there are 2 left-handed girls --> 2/20 --> simplify to 1/10
And thus, we have our answers.

B. All rectangles are parallelograms. <span />
Step-by-step explanation:
81x⁴ - 16y⁴
(9x²)² - (4y²)²
(9x² + 4y²)(9x² - 4y²)
(9x² + 4y²)(3x + 2y)(3x - 2y)
