Jeremy is playing a game where he must roll a cube numbered 1 to 6 and a color cube at the same time. The sides of the color cube are red, yellow, green, blue, white, and purple. The table shows all the outcomes of rolling the two cubes.
Outcomes 1 2 3 4 5 6
Red R, 1 R, 2 R, 3 R, 4 R, 5 R, 6
Yellow Y, 1 Y, 2 Y, 3 Y, 4 Y, 5 Y, 6
Green G, 1 G, 2 G, 3 G, 4 G, 5 G, 6
Blue B, 1 B, 2 B, 3 B, 4 B, 5 B, 6
White W, 1 W,2 W, 3 W, 4 W, 5 W, 6
Purple P, 1 P, 2 P, 3 P, 4 P, 5 P, 6
What is the probability of the number cube landing on a number less than 5 and the color cube landing on red or yellow?
+23246 Count the total number of possibilities: 36
Count the number which are red and have a number less than 5: 4
Count the number which are yellow and have a number less than 5: 4
Add these together (=8) and divide by the total number of possibilities (=36).
Probability = 8/36
