34kurt

Answer:

The probability it will land on green every time is \frac{1}{27}.

Step-by-step explanation:

We are given that a spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow.

The pointer is spun three times.

<u>As we know that the probability of an event is described as;</u>

  Probability of an event =  \frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}

Here, the favorable outcome is that the spinner will land on green every time.

So, the number of green regions = 2

Total number of regions = 3(red) + 2(green) + 1(yellow) = 6 regions

<em>Now, the probability it will land on green every time is given by;</em>

        Probability =  \frac{2}{6}\times \frac{2}{6}\times \frac{2}{6}

                           =  \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}

                           =  \frac{1}{27}

Hence, the probability it will land on green every time is \frac{1}{27}.

1 & 5 are corresponding because they are in the same place on the lines.
1 & 8 are alternate exterior because they are on opposite sides of the transversal and they are on the outside of the parallel lines.
2 & 6 are corresponding. 
2 & 7 are alternate exterior.
3 & 5 are alternate interior because they are on opposite sides of the transversal, and they are in between the parallel lines.
3 & 6 are consecutive interior angles because they are on the same side interior of the parallel lines.
3 & 8 are corresponding.
4 & 5 are consecutive interior.
4 & 6 are alternate interior.
4 & 7 are corresponding.

Hope this helps you now and in the future =)
