Question

Zoe rolls two fair six-sided number cubes. What is the probability that at least one number cube shows a 5?

Answer 1

Answer:

Probability of obtaining at least one five = 3/12

Step-by-step explanation:

Number cube have six faces.

Then two number cube have 12 faces total but independent 6 two faces

Number of 5 in a number cube is one.

Probability of obtaining a 5 in a number cube = 1/6

Probability of obtaining at least one five in the two number cube mean = probability of obtaining a five or two five

= 1/6 + 1/12

= 3/12
