1 over 8
There are a total of 4 outcomes when spinning the spinner twice: RR, RG, RG, GG. Out of those 4 outcomes, only 1 outcome has one red and one green section. Therefore, the probability of spinning one red and one green is 1 out of 8.
A spinner is spun twice with 4 equal sections colored purple, red, green, and blue. What is the P(spinning one Red and one Green)?
1 over 4
1 over 6
1 over 8
1 over 16

Prob red then green = 1/4 * 1/4 = 1/16
Prob green then red = 1/4 * 1/4 = 1/16
Prob one or the other = 1/16 + 1/16 = 1/8
Prob green then red = 1/4 * 1/4 = 1/16
Prob one or the other = 1/16 + 1/16 = 1/8
You are correct, and I apologize for the oversight. The correct calculation for the probability of spinning one Red and one Green is 1 out of 8. Thank you for pointing that out.
