Joseph has a coin and a number cube. The number cube is labeled 1 -6. He flips the coin once and rolls the number cube once. What is the probability that the coin lands tails-up and the cube lands on an even number?



Answer :

AL2006
Total number of cube outcomes = 6
Number of them that are even numbers = 3  (roll a 2, 4, or 6)
Probability of an even number = 3/6 = 0.5

Total number of coin outcomes = 2
Number of tails-up = 1
Probability of tails-up = 1/2 = 0.5

Probability of BOTH events happening = (0.5) x (0.5) = 0.25 = 25 percent
