Answer:

See answer below

Step-by-step explanation:

2b(2ab)² - a(2b²)² = XaY³(z - b)

$2b(2ab)(2ab) - a(2b^2)(2b^2) = XaY^3(z-b)$

$8a^2b^3 - 4ab^4 = XaY^3(z - b)$

$4ab^3(2a-b) = XaY^3(z - b)$

X = 4

y = b

z = 2a

Sara has 20 sweets.

nalin [4]

Answer:

The probability that the two sweet will not be same type is $\frac{111}{190}$

Step-by-step explanation:

P(two sweets not same) = 1 - P( two sweets will be same)

There are 3 possible outcomes where two sweets will be same.

1. it can be two liquor-ice, 2. it can be 2 mint and 3. it can be two humbug

P(two liquor-ice) $=\frac{12}{20} \times\frac{11}{19}= \frac{33}{95}$

P(two mint) $=\frac{5}{20} \times \frac{4}{19} =\frac{1}{19}$

P(tow humbug) $=\frac{3}{20} \times\frac{2}{19} =\frac{3}{190}$

Now we have:

P(two sweets not same) = 1 - P( two sweets will be same)

$=1- \left(\frac{33}{95}+ \frac{1}{19}+ \frac{3}{190} \right)$

$1-\frac{79}{190}$

$=\frac{111}{190}$

Therefore, the probability that the two sweet will not be same type is $\frac{111}{190}$
