<h2>Answer:</h2>

The simplified expression is given by:

                 1 over 6 to the 8th power.

                      \dfrac{1}{6^8}

<h2>Step-by-step explanation:</h2>

We are asked to simplify the expression:

6 to the negative 3rd power over 6 to the 5th power.

which is mathematically written as:

\dfrac{6^{-3}}{6^5}

Now, we know that:

\dfrac{a^m}{a^n}=\dfrac{1}{a^{n-m}}

Here,

m=-3\ and\ n=5

Hence, we get:

\dfrac{6^{-3}}{6^5}=\dfrac{1}{6^{5-(-3)}}

i.e.

\dfrac{6^{-3}}{6^5}=\dfrac{1}{6^{5+3}}

Hence, we get the simplified expression as follows:

\dfrac{6^{-3}}{6^5}=\dfrac{1}{6^8}

If the probability is 0.54 that Stock A will increase in value during the next month and the probability is 0.68 that Stock B wi
Aloiza [94]

P(A) =0.54

P(B)= 0.68

P'(A)= 1-0.54 = 0.46

P'(B)= 1- 0.68 = 0.32

The probability of neither of both event will occur:

= P'(A)×P'(B)

=0.46 × 0.32

=0.1472
