Answer: Our required probability is 0.56.

Step-by-step explanation:

Since we have given that

In urn I :

Number of red chips = 5

Number of white chips = 4

In urn 2 :

Number of red chips = 4

Number of white chips = 5

Two chips are drawn simultaneously from urn I and placed into urn II. Then a single chip is drawn from urn II.

Probability that the chip drawn from urn II is white is given by

P(E₁) = \dfrac{1}{2} = P(E₂)

P(W|E₁) = \dfrac{4}{9}

P(W|E₂) = \dfrac{5}{9}

So, by "Bayes theorem ", we get that

P(E_2|W)=\dfrac{0.5\times \dfrac{5}{9}}{0.5\times \dfrac{4}{9}+0.5\times \dfrac{5}{9}}\\\\P(E_2|W)=\dfrac{5}{9}=0.56

Hence, our required probability is 0.56.

Write each expression in simplest form. (x²/x⁻¹¹)¹/₃
aleksklad [387]

The result of simplifying the expression (x²/x⁻¹¹)¹/₃ using the exponent rules is \sqrt[3]{}(x¹³)

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(x²/x⁻¹¹)¹/₃

Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:

(x⁽²⁻⁽⁻¹¹⁾)¹/₃

(x⁽²⁺¹¹⁾)¹/₃

(x¹³)¹/₃

Using the power of a power rule that indicates that: the exponent result will be the multiplication of these powers, we have:

x⁽¹³*¹/₃⁾

x⁽¹³/₃⁾

As we have a fractional exponent, you must convert the exponent to root:

\sqrt[3]{}(x¹³)

<h3>What is an exponent?</h3>

In mathematics an exponent is the number of time that a number, called (base) is multiplied by itself. It is also called, power or index.

Example: 3² = 3*3 = 9
