Aspinner can land on either red, blue, green, or yellow (the wedges are the same size). you spin twice. what is the probability that you land on blue on your first spin and on yellow on your second spin?

There are four (4) colors to choose from. The number of sample space is equal to 4. With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4. Similarly, the probability of landing on yellow on the second spin is 1/4. 

            P = (1/4)(1/4)
  
              P = 1/16

1/16
