Tanya has several different ways she likes to walk home. One route takes 20 minutes, two of the routes take 30 minutes, and two take 40 minutes.

Tanya randomly chooses a route to walk home.

What is the probability, to the nearest percent, that it will take her 30 min to walk home?

50% because there are 4 routes and 2 take 30 minutes, 2/4 = 50/100 = 50%
