### Ian's E-49 Question#1

Find each probability if you spin the spinner once.

1.P(red)= 1-possible outcomes
5- total possible outcomes=20%
I divided the possible outcomes and total of possible outcomes then I multiply it to 100 to become a percent of my answer.

1/5=0.2=20%

2.P(green)1/5 =20%

I did it as the first one I divided the possible outcomes and the total possible outcomes then I multiply it to 100 to get the percent which is 20%

1/5=0.2=20%

3.P(blue or yellow)2/5=40%

This is the same as the other ones I divided the possible outcomes which is 2 to the total possible outcomes which is 5 then I multiply it to 100 to become a percent which is 40%.

2/5=0.4=40%

4.P(not yellow)4/5=80%

First I take the possible outcomes which is 4 and the total possible outcomes which is 5 then I divided it.Then I multiply it to 100 to become a percent which is 80%.

4/5=0.8=80%

5.P(not red)4/5=80%

what I did is like this first I look for the othr thats not red. Then I found the possible outcomes which is 4 and the total possible outcomes which is 5.Then I multiply it to 100 to become a percent.

4/5=0.8=80%

6.P(blue or red or yellow)3/5=60%

I count the blue red yellow which is the possible outcomes that is 3 and I look for the total possible outcomes which is 5.I multiply them to know the ratio then I divided it to 100 to become a percent.

3/5=0.6=60%

My own questions:

1(blue or brown)

2P(red or yellow)

3P(blue or yellow)

4P(red)

1. 2/5=0.4=40%

2. 2/5=0.4=40%

3. 2/5=0.4=40%

4. 1/5=0.2=20%
