Question

Ashleigh can choose from one of 6 different routes to get to work. The routes are listed below.

• Main St.

• Route 6

• Hilltop Drive

• Medical Avenue

• Highway 220

• Friendship Boulevard


If she chooses one route at random, what is the probability that she will choose either Hilltop Drive or Medical Avenue to get to work?

Answer 1

1 /3

Explanation:

Total Number of routes = 6

Probability = required outcome / Total possible outcomes

Probability of any one of the routes :

Required outcome / Total possible outcomes

Probability of choosing any one of the routes = 1/6

Hence,

Probability of choosing either Hilltop. Drive or medical avenue =

1/6 + 1/6 = (1 + 1) / 6 = 2 /6 = 1/3
