1/8 because if I choose a black one first then put it back there isn't a 50% chance
Option C:
is the value of a and b
Explanation:
Given that the expression 
We need to determine the value of a and b
Let us consider the term
and take the prime factorization of the term 648
Thus, we have,
648 divides by 2,

324 divides by 2,

162 divides by 2,

81 divides by 3,

27 divides by 3,

9 divides by 3,

Thus, we have,

Therefore, equating the powers of 2 and 3, we get,

Hence, the value of a and b is 3 and 4
Thus, Option C is the correct answer.
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
The reason how the expression are equivalent given below:
<h3>What is Distributive Property?</h3>
Multiplying a number by a sum or difference is the same as multiplying by each number in the sum or difference and then adding or subtracting.
The Complete question is:
How can you use distributive property to write an expression equivalent to the one given above? Use reasoning to explain how you know the expressions are equivalent.
Distributive property represents distribute the outside number among the number or digits in parenthesis.
For Example: Solve the expression 7(20 + 3) using the distributive property of multiplication over addition.
When we solve the expression 7(20 + 3) using the distributive property,
we first multiply every addend by 7.
This is known as distributing the number 7 amongst the two addends and then we can add the products.
This means that the multiplication of 7(20) and 7(3) will be performed before the addition.
Hence, 7(20) + 7(3) = 140 + 21 = 161.
