In a large school district, for every one male teacher, there are three female teachers. Four teachers are selected at random to receive a gift card. To estimate the probability of the number of male teachers who would be selected to receive a gift card, use simulation with a spinner. One spin on the spinner represents one teacher.
​A. Describe a spinner that could be used to simulate the situation, and specify what outcome on the spinner could represent a male teacher receiving the gift card.
