Question

b. What is the sample space if you spin the spinner TWO TIMES?RedYellowBlueRedYellowBluec. One spin, P(red)(fraction)d. Two spins, Pared then blue)(decimal to 2 places)e. Two spins, P(yellow or red)=% (percent to 1 decimal place)

Answer 1

Hanna, this is the solution:

As you can see there are three equal sectors colored yellow, blue, red, therefore, the sample space for spinning the spinner two time is:

{yellow-yellow, blue-yellow, red-yellow, red-blue, red-red, blue-blue}

Spin the spinner one time:

• Red = 1/3 or 0.33

,

• Blue = 1/3 or 0.33

,

• Yellow = 1/3 or 0.33

Spin the spinner a second time:

• Red - Red = 1/3 * 1/3 = 1/9 or 0.11

,

• Red - Blue = 1/3 * 1/3 = 1/9 or 0.11

,

• Red - Yellow = 1/3 * 1/3 = 1/9 or 0.11

,

• Blue - Blue = 1/3 * 1/3 = 1/9 or 0.11

,

• Blue - Red = 1/3 * 1/3 = 1/9 or 0.11

,

• Blue - Yellow =1/3 * 1/3 = 1/9 or 0.11

,

• Yellow - Yellow = 1/3 * 1/3 = 1/9 or 0.11

,

• Yellow - Red = 1/3 * 1/3 = 1/9 or 0.11

,

• Yellow - Blue = 1/3 * 1/3 = 1/9 or 0.11
