Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles

Reasons:
The process of multiplication of factors using a model includes;
- Creating a table that have the number of rows and columns equal to the values in the denominator of the two fractions respectively
- Shading the number of columns given by the numerator of the fraction that has a denominator equal to the number of columns in the table
- Shading the number of rows given by the numerator of the fraction that has a denominator equal to the number of rows in the table
- Ensuring that the common area are shaded to a different color

Step-by-step explanation:
You must use the laws of exponents.
7)

When you raise a fraction to an exponent, raise the numerator and the denominator to that exponent.

When you raise a product to an exponent, raise each factor to that exponent.
When you raise an exponent to an exponent, multiply the exponents.


8)

To divide powers with the same base, subtract the exponents. Remember that a plain variable, such as w is the same as w^1.
