Samantha makes a maze for her pet gerbil. At one point in the maze, the path splits and the gerbil has an equally likely chance to choose either the left branch or the right branch. Samantha places her gerbil in the maze 10 times in a row and records the number of times the gerbil chooses the left branch.

What is the experimental probability that the gerbil will choose the left branch of

the maze on the next trial?

• 25%

• 50%

• 70%

• 75%
