Answer:

The probability of not drawing a black marble is 8/10 and the probability of drawing a red marble is 3/10.

Step-by-step explanation:

There are 10 marbles altogether, and 8 of them are not black marbles, and only 3 of them are red.

Since you are not allowed to draw a black marble, then you have only 7 ways to draw either a blue or a red marble. The sum of all marbles is 10. So the probability of not drawing a black marble is 7/10 and the probability of drawing a red marble is 2/10 or 1/5.

How do you use exponents in a test
katrin2010 [14]

Answer:

An exponent is a number that is to a certain value, like 5^2.

The ^2 means multiply by itself by itself ONCE,

so it would be 5x5.

5^3 means multiply it by itself TWO TIMES,

and going on and on.

Let's say you have a test and the question it's asking is to simplify 5^4.

It's 5x5x5x5, multiplying it by itself FIVE TIMES.

Hope this helped!
