ANSWER

P(not \: B) =  \frac{1}{4}

EXPLANATION

If A and B are independent events, then

P(A and B)=P(A)×P(B)

\frac{3}{10}  =  \frac{2}{5}  \times  \: P(B)

Multiply both sides by;

\frac{5}{2}

\frac{5}{2}  \times  \frac{3}{10}  =   \frac{5}{2}  \times \frac{2}{5}  \times  \: P(B)

\frac{3}{4}  =P(B)

P(not \: B) = 1 - P(B)

P(not \: B) = 1 - \frac{3}{4}

P(not \: B) =  \frac{1}{4}

Simplifying an Expression with the Numerator and the Denominator Raised to a Power
slamgirl [31]

Answer:

The answer to your question is    the second option     \frac{1}{x^{48}y^{36}z^{6}}

Step-by-step explanation:

Expression

                       [\frac{(x^{2}y^{3})^{-2}}{(x^{6}y^{3}z)^{2}}]^{3}

Process

1.- Divide the fraction in numerator and denominator

a) Numerator  

 [(x²y³)⁻²]³ = (x⁻⁴y⁻⁶)³ = x⁻¹²y⁻¹⁸

b) Denominator

 [(x⁶y³z)²]²= (x¹²y⁶z²)³ = x³⁶y¹⁸z⁶

2.- Simplify like terms

a) x⁻¹²x⁻³⁶ = x⁻⁴⁸

b) y⁻¹⁸y⁻¹⁸= y⁻³⁶

c) z⁻⁶

3.- Write the fraction

        \frac{1}{x^{48}y^{36}z^{6}}

a+b+c=180,  \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.
