 Problem: A spinner has 4 equal sectors colored yellow, blue, green and red. What are the chances of landing on blue after spinning the spinner? What are the chances of landing on red?

Okay to find the probability you count the number of possible outcomes and that is your denominator, then you would count the number of ways the explained event could occur and that is your numerator. So for the question below you would count the number of colors on the spinner (4) and then you would find how many times there is a blue sector (1) so the probability of landing on blue is 1/4. It's that same for red.
