Two 6-sided dice, one red and one green, are rolled. What is the probability that the red die shows an odd number and the green die shows a number that is a perfect square?
Red Die
Odd numbers: 1, 2, 3, 4, 5, 6
Probability: 3 / 6 = 1 / 2
Green Die
Perfect Squares: 1, 2, 3, 4, 5, 6
1 is a perfect square as √1 = 1
4 is a perfect square as √4 = 2
Probability: 2 / 6 = 1 / 3
1 / 2 * 1 / 3 = 1 / 6
