Answer:

The probability that the marble drawn will not be blue is 7/9

Step-by-step explanation:

We have been given that

Number of blue marbles = 8

Total number of marbles = 8 + 6 + 12 +10 = 36

Probability of an event E is given by the formula

P(E)=\frac{n(E)}{n(S)}

Here, we have

n(E) = 8

n (S) = 36

Hence, the probability of getting a blue marble is

P(E)=\frac{8}{36}\\\\=\frac{2}{9}

Therefore, probability that the marble drawn will not be blue is given by

1-P(E)\\\\=1-\frac{2}{9}\\\\=\frac{7}{9}

Total Marbles = 8 + 6 + 12 + 10 = 36

Probability the marble is blue = 8/36

Inverse this to get the probability of the marble not being blue

Probability of the marble not being blue = 28/36 = 7/9

What is the base for the expression -6 to the power of 4
natima [27]

For this case we have that by definition it is fulfilled:

a ^ b

Where:

a: It is the base

b: It is the exponent

So, if we have the following expression:

-6 to the power of 4, is equivalent to: (-6) ^ 4

So we have to:

-6: It is the base

4: It is the exponent

Answer:

-6: It is the base

4: It is the exponent
