Answer:
1/4
Step-by-step explanation:
Possible outcomes from rolling the cube that satisfy the "greater than 3" criterion are {4, 5, 6} out of a total of six possibilities {1, 2, 3, 4, 5, 6}. Thus, the probability of rolling a number greater than 3 is 3/6, or 1/2.
Probability of flipping heads is 1/2.
These are entirely independent events. Thus, the joint probability is (1/2)(1/2), or 1/4.
