Question

Use the Counting Principle to find the probability. rolling a 5 on each of 2 number cubes

Answer 1

Answer:

2/12

Step-by-step explanation:

Rolling a 5 on one die the probability is 1 out of 6 or 1/6 so when you add the second die the probability increases as well as the number of outcomes so you have 1/6+1/6 or 2/12. hope this helps

Answer 2

Answer:

1/36

Step-by-step explanation:

A cube has six sides.  On number cubes (also called dice), the sides are numbered 1 through 6.  So the probability of rolling a 5 on either cube is 1/6.  The probability of rolling a 5 on both cubes is:

P(A and B) = P(A) × P(B)

P(A and B) = 1/6 × 1/6

P(A and B) = 1/36
