Probability of Compound Events

Make a sample space of the compound event: color and size of shirt. (small, medium, large and red, blue, green ). Use a list. s- small, m - medium, l - large r- red, b - blue, g - green srsbsg mr lr mb lb mg lg There are 9 outcomes EX1) What is the probability of picking a medium blue shirt?

EX2) Mark, Jane and Fred have been chosen to receive a gift certificate. Use a list to determine the sample space of the different ways they could receive their gift certificate. Mark Jane Fred MarkJaneFred MarkJaneFred MarkJaneFred There are 6 outcomes What is the probability of Jane being the first to receive her certificate? =
