Suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a red marble followed by a blue marble? The multiplication rule says to use P(red) P(blue). Using this information and the Text Editor, answer the questions below: Describe the probability of finding a red marble. Describe the probability of finding a blue marble. Describe the process of finding the probability of finding a red marble followed by a blue marble. What effect did putting the first marble back in the box have on the problem? Describe the probability of finding a red marble followed by the blue marble. Explain why this is the case. I'm seriously bad at math please help me out

The correct answer is 1.07x10^-2.

In order to find this, we first multiply the lead numbers.

1.18 * 9.1 = 10.7

Then we can simply add the exponents together.

3 + -6 = -3.

Now we put it all together.

10.7x10^-3

However, our number has to be less than 10. So we mov the decimal place one and add one to the exponent.

1.07*10^-2
