Question

Francine rolls two 6-sided number cubes. What is the probability that she rolls

a sum equal to 6? Use the diagram of the sample space to help you.

Answer 1

Option D

Explanation:

Probability of an event =
`\frac{\text{Favorable outcome}}{\text{Total number of outcomes}}`

Favorable outcome = sum of numbers is 6 on rolling two cubes

= (5 + 1), (4 + 2), (3 + 3), (2 + 4), (1 + 5)

Therefore, number of rolls that she gets a sum of 6 = 5

Total number of outcomes = 6 × 6 = 36

Therefore, probability that she rolls a sum equal to 6 =
`(5)/(36)`

Therefore, Option D will be the answer.
