Aspinner has 4 equal sections. red, blue, yellow and green. maria spins the spinner and tosses a coin. which shows the sample space for spinning and tossing the coin?

Sample space is the list of outcomes. To find out the list of outcomes of the problem stated above, let us use the Theoretical Probability.

Theoretical Probability=   favorable Outcome
                                       total possible outcomes
Let us suppose the following:
      P(blue) = no. of ways to land on blue 
                              total no. of colors
                   = 1/4
                   = .25
 To get the percentage of the outcome, let us multiply .25 with 100
                   =.25 x 100
                   = 25%
This means, 1 out 4 is the probability of blue to occur.
The same thing happens to red, green and yellow. They have 1 possible favorable outcome out of 4 possible outcomes.
To summarize, look at the sample space below: (it is better to put them on a table)

Color                                     Outcome
blue                                            1
red                                             1
green                                         1
yellow                                         1

Here is the probability: Each color may occur once out of 4.
